Name__________________________________ Formula of a Compound 1. Useful only if it correctly represents the substance. 2. The composition is determined in chemical analysis. 3. The formula then is derived by atomic theory and chemical bonding methods. 4. A chemical formula is a qualitative and quantitative description of the composition of a pure substance, either as element or a compound. Naming Binary Compounds Two types of Binary Compounds A. Combining a metal and a non-metal 1. The metallic element is usually named and written first-this is at times called the cation. Example: KCl -The cation is K, so the name Potassium is written 2. The non-metal, which is called the anion, is made from the root word of the name of the element plus an -ide ending. Cl is chlorine, the root is chlor, then add the -ide ending to write the word chloride. 3. Place both names together: Potassium chloride Problem Section #1 Directions: Write the non-metal ion names for the following 1. Nitrogen __________________ 2. Oxygen ___________________ 3. Sulfur ____________________ 4. Fluorine __________________ 5. Chlorine __________________ 6.

Fielder Lewis Research Center SUMMARY The conductivities of single crystals of calcium and strontium fluoride were deter­ mined. In the extrinsic region (impurity controlled), the specific conductivity of each crys­ tal may differ. The extrinsic conductivities KI for the normal process of point-defect migration for two calcium fluoride (CaF2) crystals (A and B) between 430' and 535' C were as follows (in ohm-' cm-l): for A, KI = 1.11*0. O1xlO-l exp - (16 50&100/RT) and for B, KI = 1.21*0. OIXIO-l exp - (16 500*100/RT) where R is the gas constant (cal/(deg)(mole)) and T is the absolute temperature (deg). The extrinsic conductivity of strontium fluoride (SrF2) between 360' and 410' C was KI = 1.22&0.05X10-2 exp - (17 40&900/RT). Only one intrinsic region was observed for two calcium fluoride crystals between 645' and 830' C or for strontium fluoride between 580' and 760' C.

    While There Are Many Thousands of Different Chemical Compounds There

    NAMING CHEMICAL COMPOUNDS & WRITING CHEMICAL FORMULAS While there are many thousands of different chemical compounds there is a very definite system of nomenclature whereby we can name or write chemical formulas for most compounds. We divide the compounds into two main types – binary compounds and ternary compounds. I. Binary Compounds All true binary compounds contain only two elements. The name of every binary compound ends with “ide.” Binary compounds come in three types. They are: Type I ………. the metal forms only one type of cation Type II ……… the metal forms two or more types of cations Type III …….. contains only nonmetals We will look at each type, one at a time. Type I Binary Compounds For Type I binary compounds the metal present can be found in either Group 1 or Group 2 on the periodic table. The naming system for this type of compound is quite simple and is found below. Rules for naming Type I binary compounds 1. The cation is always name first and the anion second. 2. A simple cation (obtained from a single atom) takes its name from the name of the element. 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters “IDE.” 4. Write the name for the compound by combining the names of the ions. When naming Type I binary compounds: name of first element root + ide The root is merely an abbreviation for the name of the second element. The roots of the most commonly used elements are listed in the following table.

  • Strontium Fluoride (Srf2)

    Strontium Fluoride (Srf2)

    Strontium Fluoride (SrF2) MICHAEL E, THOMAS Applied Physics Laboratory The Johns Hopkins University Laurel, Maryland Strontium fluoride offers a wide range of transparency, from the ultravio- let to the long-wave infrared (0.13 to 11 /zm), with low reflectance loss and low dispersion. This combination of broad transparency and low dispersion is rare in optical-window materials used in infrared systems. Like BaF 2, it allows experimenters to conveniently perform initial system alignment in the visible and then switch to the IR with only minor correction of the optical components. Furthermore, strontium fluoride has good surface hardness (Knoop scale 150 kg/mm 2) and is not hygroscopic. It has a flexure strength between those of CaF 2 (90 MPa) and BaF 2 (27 MPa). Strontium fluoride is a cubic crystal with the fluorite structure, space group Fm3m (Oh),5 with four formula units per unit cell. The lattice constant is 5.7996 A, giving a theoretical density of 4.277 g/cm 3. The atomic arrange- ment is strontium atoms occupy the 4(a) sites (m3m or Oh symmetry), and the fluorine atoms occupy the 8(c) sites (43m or Ta symmetry). Melting point is 1750 K. Ultraviolet reflectance of bulk SrF 2 was measured by Ganin et al. [ 1] up to 20 eV at room temperature and liquid-helium temperature. Rubloff [2] measured the room-temperature reflectance up to 36 eV. Unfortunately, these measurements are not reduced to optical constants. However, similar mea- surements from 10 to 36 eV by Nisar and Robin [3] have been reduced to optical constants using the Kramers-Kronig relation.
  • Unit 10 Chemical Formulas and Valence

    Unit 10 Chemical Formulas and Valence

    Unit 10 Chemical Formulas and Valence INTRODUCTION The formula of a compound describes the exact composition of a molecule of the compound. These formulas oftentimes were determined by tedious analysis of the compound itself. A simpler method of determining the chemical formula of a compound is to use the concept of valence. This method makes it much easier to predict the formulas for compounds even if we do not have a sample of the compound to physically work with. OBJECTIVES 1. The student will define or identify the terms associated with valence as described in this unit. 2. The student will assign valence to atoms and radicals using the rules given in this unit and a Periodic Chart. 3. The student will use valence to write the correct formula for a compound. DISCUSSION A. Valence The valence of an atom or group of atoms is a number that indicates the charge that an atom or group of atoms has when involved in a compound. The charge may be positive or negative and have values as low as a negative four (-4) to a positive seven (+7). Atoms or groups of atoms with a positive valence are called cations. Atoms or groups of atoms with a negative valence are called anions. The valence of an atom is related to the number of valence electrons and thus to the position of an atom on the Periodic Chart. The valence is written as a superscript to the atom. The number is preceded by a sign to indicate whether the valence is positive (+) or negative (-).

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract For developing coating materials, the fluorides of scandium, lanthanum, strontium, barium, mag- nesium and aluminum were produced from their oxides and chlorides by means of exposure to chlorine trifluoride gas at temperatures between room temperature and 700˚C. The metal chlo- rides could be easily fluorinated even at room temperature, while the metal oxides required tem- peratures higher than 300˚C. After the heating in ambient hydrogen at 1100˚C, the fluorides of lanthanum and barium showed very low weight losses at 1100˚C, although the weights of the other fluorides significantly decreased. These materials may work as protective films against corrosive and high temperature environments, particularly when using the chlorine trifluoride gas. Keywords Metal Fluoride, Metal Oxide, Chlorine Trifluoride, Synthesis, Coating Film Material 1. Introduction Chemical vapor deposition (CVD) can produce various high quality and functional material films [1]. In the CVD reactor, a film is formed not only on the substrate surface, but also on the surface of various reactor parts, such as the susceptor, gas distributor and exhaust.
