Unit 4.2 Inorganic Binary Compounds Type I Unit 4.2 Inorganic Binary Compounds Type I How does shorthand work? Shorthand was a very popular way of recording speech, especially in dictating letters and in court testimony. Instead of trying to write out all the words, the person taking the dictation would use a set of symbols that represented syllables or words. The pages above show a shorthand version of “A Christmas Carol” written by Charles Dickens. Unless you know shorthand, the passage is meaningless. But knowing shorthand allows you to read this classic story. Different professions also use a type of shorthand in communication to save time. Chemists use chemical symbols in combination to indicate specific compounds. There are two advantages to this approach: 1. The compound under discussion is clearly described so there can be no confusion about its identity. 2. Chemical symbols represent a universal language that all chemists can understand, no matter what their native language is. Writing Formulas for Binary Ionic Compounds If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Because the overall compound must be electrically neutral, decide how many of each ion is needed in order for the positive and negative charge to cancel each other out. Consider the compound aluminum nitride. The ions are: Al+3 N-3 Since the ions have charges that are equal in magnitude, one of each will be the lowest ratio of ions in the AlN formula. Remember that the total charge must be equal to zero. (+3) + (-3) = 0 The ions for the compound lithium oxide, two lithium ions are required to balance out the charge of one oxide ion. Li+1 O-2 Li2O Again the total charge must be equal to zero. 2(+1) + (-2) = 0 An alternative way to writing a correct formula for an ionic compound is to use the crisscross method. In this method, the numerical value of each of the ion charges is crossed over to become the subscript of the other ion. Signs of the charges are dropped. Shown below is the crisscross method for aluminum oxide. The red arrows indicate that the 3 from the 3+ charge will cross over to Al+3 O-2 become the subscript of the O. The 2 from the 2− charge will cross over Al2O3 to become the subscript of the Al. The total charge must be equal to zero. 2(+3) + 3(-2) = 0 Be aware that ionic compounds are empirical formulas and so must be written as the lowest ratio of the ions. In the case of aluminum nitride, the crisscross method would yield a formula of Al3N3, which is not correct. It must be reduced to AlN. Following the crisscross method to write the formula for lead (IV) oxide would involve the following steps: +4 -2 Pb O The crisscross first yields Pb2O4 for the formula, but that must be reduced to the lower ratio and Pb2O4 PbO2 is the correct formula. PbO2 The total charge must be equal to zero. (+4) + 2(-2) = 0 Inorganic Binary Compounds Type I An inorganic binary compound type I is a compound composed of a monatomic metal cation and a monatomic nonmetal anion. Monatomic meaning that it is a one atom ion. These would include ions such as those made from Alkali metals, alkali Earth metals, or Halogens. It may include other ions. Naming Binary Ionic Compounds When examining the formula of a compound in order to name it, you must first decide what kind of compound it is. For an inorganic binary compound type I, it must be made of two types of atoms only! A metal will always be the first element in the formula, while a nonmetal will always be the second. When naming, the metal cation is named first. Remember that the positive metal ions keep the name given to the metal. For example the sodium ion, Na+1, is called sodium. The nonmetal anion is named second. Monatomic, or one atom negative ions always drop the ending and add –ide to the name. For example the ion made from chlorine, Cl-1, is called chloride. The compound made from one sodium ion and one chloride ion, NaCl, is called sodium chloride. Subscripts are used to balance the charge to equal zero net charge for the molecule. Subscripts in the formula do not affect the name. The following chart shows three examples. Naming Inorganic Binary Compounds Types I Formula Name Net charge KF Potassium fluoride (+1) + (-1) = 0 Na3N Sodium nitride 3(+1) + (-3) = 0 Ca3P2 Calcium phosphide 3(+2) + 2(-3) = 0 Notice that in each of the formulas above, the overall charge of the compound is zero. Potassium ion is K+1, while fluoride ion is F-1. Since the magnitude of the charges is equal, the formula contains one of each ion. K+1 F-1 (+1) + (-1) = 0 KF This would also be the case for a compound such as magnesium sulfide, MgS, in which the ions are Mg2+ and S2-. Mg+2 S-2 (+2) + (-2) = 0 MgS In order to make a neutral compound, three of the +1 sodium ions are required in order to balance out the single -3 nitride ion. Na+1 N-3 The crisscross method is used with subscripts to balance the compound to zero net charge. 3(+1) + (-3) = 0 Na3N So the Na is given a subscript of 3. For calcium phosphide, the calcium ion is Ca+2, while the phosphide ion is P-3. The least common multiple of 2 and 3 is 6 (3 x +2 = 6, and 2 x -3 = 6). To make the compound neutral, three calcium ions have a total charge of +6, while two phosphide ions have a total charge of -6. The Ca is given a subscript of 3, while the P is given a subscript of 2. +2 -3 Ca P 3(+2) + 2(-3) = 0 Ca3P2 Summary A binary ionic compound is a compound composed of a monatomic metal cation and a monatomic nonmetal anion. Monatomic ion is a one atom ion. Formulas for binary compounds begin with the metal followed by the non-metal. The metal cation keeps the name of the metal. The non-metallic anion is named by dropping the end of the element and adding –ide. Positive and negative charges must cancel each other out. For binary compounds, it is not necessary to indicate the number of ions in the compound using subscripts. Ionic compound formulas are written using the lowest ratio of ions. Review 1.

Terminology: chemistry is a noun (object), but could refer to an object of study or prac- tice, etc. As an object of study,chemistry could refer to what is expected to be known by a novice, all that is known, all that may be known, etc; as a practice, chemistry could refer to practical applications, theoretical principles, processes where substances change called chemical reactions, etc. The word reasonable might connote logic, understand- ing, ethical practice, demand, etc. One might logically conclude that the subject of chemistry should be understandable, or that the field of chemistry should be non-productive (if it is reasonable to assume that chemistry is harmful to the environment, say), etc. This example is not meant to be totally trivial. Communication involves common under- standing of terminology,construction (syntax) and meaning (semantics). Forexample, the word "add" may mean different things depending on the context; e.g. calculators (add twointegers), travelagents (add the mileage, add a flight, total the cost). Clear definitions and logical thinking are essential to science. 3. There seems to be an implicit assumption that Alice wants to go somewhere.

  • The Energy Landscape Concept and Its Implications for Synthesis Planning
    Pure Appl. Chem. 2014; 86(6): 883–898 Conference paper Martin Jansen* The energy landscape concept and its implications for synthesis planning Abstract: Synthesis of novel solids, in a chemical sense, is one of the spearheads of innovation in materials research. However, such an undertaking is substantially impaired by lack of control and predictability. We present a concept that points the way towards rational planning of syntheses in solid state and materials chemistry. The foundation of our approach is the representation of the whole material world, i.e., the known and not-yet-known chemical compounds, on an energy landscape, which implies information about the free energies of these configurations. From this it follows at once that all chemical compounds capable of existence (both thermodynamically stable and metastable ones) are already present in virtuo in this landscape. For the first step of synthesis planning, i.e., the identification of candidates that are capable of existence, we computa- tionally search the respective potential energy landscapes for (meta)stable structure candidates. Recently we have extended our techniques to finite temperatures and pressures and calculated phase diagrams, including metastable manifestations of matter, without resorting to any experimental pre-information. The conception developed is physically consistent, and its feasibility has been proven. Applying appropriate experimental tools has enabled us to realize, e.g., elusive Na3N, including almost all of its predicted polymorphs, many years after the predictions were published. Keywords: calculation of phase diagrams; global searches; inorganic materials synthesis; IUPAC Congress-44; local ergodicity; solid state chemistry; structure prediction; synthesis from atoms. DOI 10.1515/pac-2014-0212 Introduction The lines of action called “analysis” and “synthesis” continue to constitute the foundation of chemistry, providing it with genuine and distinct characteristics in a time of increasing overlap among the various dis- ciplines of natural sciences.

  • Chapter 3: Ions, Ionic Compounds, and Nomenclature
    37 Chapter 3: Ions, Ionic Compounds, and Nomenclature. An ion is a small particle having an electrical charge. Ions are either single, charged atoms (simple ions), or small charged “molecules” (polyatomic ions). Examples of simple ions are Na+, Ca+2, Cl-, and S-2. Examples of polyatomic ions are + !2 ! NH4 , CO3 , and OH . Positively charged ions are called cations (pronounced cat- eye-ons) while negatively charged ions are called anions (pronounced an-eye-ons). In many cases, the elements position on the periodic table will help you determine the Kind of ion formed (anion or cation) and the size of the ionic charge. Look at the periodic table (PeriodicTable.pdf or the equivalent). Starting with boron (atomic number 5) and continuing downwards and to the right to astatine (atomic number 85), there is a bold “staircase” shaped red line. Elements to the left of this line are metals, and commonly form cations. Elements to the right of this line are non-metals, and commonly form anions. Some of the elements adjacent to the line are called “metalloids”, but this distinction doesn’t help us, so don’t concern yourself with it. Starting on the left of the periodic table, we see groups labeled “I A”, “II A”, III B”, and so on. On some newer versions of the periodic table, the groups are numbered 1 - 18. I will use the older version, and show the new group numbers in parenthesis. The elements in any particular group tend to form ions with characteristic charges. Please note, some elements are capable of having a range of electrical charges, and therefore form different ions.
