    Post-16 Induction C GCSE to A Level Chemistry - Bridging work - H Name : _______________________________ E M I ALL sections should be completed Bring this booklet to your first chemistry lesson in September. S T R Y 1 | P a g e INTRODUCTION Welcome to chemistry. In choosing to study chemistry you will develop many useful lifelong transferable skills, in addition to developing a deeper understanding of the subject. This booklet is designed to prepare you for your first year of study and hopefully answer some of the questions you may have at this stage. The first section gives some useful information about the subject, the details of your course, and gives you the opportunity to see course overview. You will typically have two chemistry teachers; (covering organic and inorganic modules), and lessons will take place in the Lycett building (GL0.02 to GL0.05). Contact me (subject leader) by e-mailing [email protected] over the summer if you have any questions. The second section (from page 6) is designed to review some of the work you will have covered at GCSE and make links with the new material you will cover in your first year of A-level chemistry. A lot of the material we cover in year 12 chemistry you will recognise from GCSE, however, we will build on, and extend your knowledge and understanding in each area. It would be advantageous for you to complete this booklet over the summer (use the answers at the back to self-mark) so that your subject knowledge is fresh when you start in the autumn.

  • Mendeleev's Periodic Table of the Elements the Periodic Table Is Thus
    An Introduction to General / Inorganic Chemistry Mendeleev’s Periodic Table of the Elements Dmitri Mendeleev born 1834 in the Soviet Union. In 1869 he organised the 63 known elements into a periodic table based on atomic masses. He predicted the existence and properties of unknown elements and pointed out accepted atomic weights that were in error. The periodic table is thus an arrangement of the elements in order of increasing atomic number. Elements are arranged in rows called periods. Elements with similar properties are placed in the same column. These columns are called groups. An Introduction to General / Inorganic Chemistry The modern day periodic table can be further divided into blocks. http://www.chemsoc.org/viselements/pages/periodic_table.html The s, p, d and f blocks This course only deals with the s and p blocks. The s block is concerned only with the filling of s orbitals and contains groups I and II which have recently been named 1 and 2. The p block is concerned only with the filling of p orbitals and contains groups III to VIII which have recently been named 13 to 18. An Introduction to General / Inorganic Chemistry Groups exist because the electronic configurations of the elements within each group are the same. Group Valence Electronic configuration 1 s1 2 s2 13 s2p1 14 s2p2 15 s2p3 16 s2p4 17 s2p5 18 s2p6 The type of chemistry exhibited by an element is reliant on the number of valence electrons, thus the chemistry displayed by elements within a given group is similar. Physical properties Elemental physical properties can also be related to electronic configuration as illustrated in the following four examples: An Introduction to General / Inorganic Chemistry 1.

Radiographers, environmental chemists and archaeologists all make use of specific isotopes in their work. Analytical chemists use UV/visible spectra and flame emission spectra to help characterise substances and colorimetry as a quantitative analytical technique. The origin of colour in compounds is of great importance in the dye-, pigment-, and paint-based industries and to development chemists researching new products. The Atom All elements are made of atoms. Atoms are made up of 3 types of particle. These are protons, neutrons and electrons. Electrons have -1 charge. They move around the nucleus in orbitals, which take up most of the volume of the atom. Most of the mass of the atom is concentrated in the nucleus. The nucleus is very small in comparison to the whole atom. The nucleus is where you find the protons and neutrons. The mass and charge of these subatomic particles is really small, so relative mass and relative charge are used instead. The table shows the relative masses and charges of protons, neutrons and electrons. Subatomic particle Relative mass Relative Charge Proton 1 +1 Neutron 1 0 Electron 1/2000 -1 3 | C h e m i s t r y Atomic Number and Mass Number You can figure out the number of protons, neutrons and electrons in an atom from the nuclear symbol.

  • Make an Atom Vocabulary Grade Levels
    MAKE AN ATOM Fundamental to physical science is a basic understanding of the atom. Atoms are comprised of protons, neutrons, and electrons. Protons and neutrons are at the center of the atom while electrons live in lobe-shaped clouds outside the nucleus. The number of electrons usually matches the number of protons, yielding a net neutral charge for the atom. Sometimes an atom has less neutrons or more neutrons than protons. This is called an isotope. If an atom has different numbers of electrons than protons, then it is an ion. If an atom has different numbers of protons, it is a different element all together. Scientists at Idaho National Laboratory study, create, and use radioactive isotopes like Uranium 234. The 234 means this isotope has an atomic mass of 234 Atomic Mass Units (AMU). GRADE LEVELS: 3-8 VOCABULARY Atom – The basic unit of a chemical element. Proton – A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign. Neutron – A subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen. Electron – A stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. Orbital – Each of the actual or potential patterns of electron density that may be formed on an atom or molecule by one or more electrons. Ion – An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

    Topic: Atoms and the Periodic Table Atoms • the basic building blocks of all substances • 92 different naturally-occurring types of atom • the smallest amount of any element we can have Fun Facts: One cubic centimetre of air contains around 90 million million atoms. Half a million (500,000) atoms lined up shoulder to shoulder could hide behind a human hair. If you wanted to see the atoms in a drop of water you’d have to enlarge it until it was 24km across If Julius Caesar’s dying breath was evenly distributed through the atmosphere, each time you breathe in you’d take in 100 molecules of it. Structure of an atom orbiting electrons nucleus: cluster of protons and neutrons Protons, neutrons and electrons are sub-atomic particles with different properties: Sub-atomic particle Charge Mass Proton + 1 1 Neutron 0 1 Electron - 1 0.0005 An atom has no overall charge because… Rule 1 number of protons = number of electrons An atom is mostly empty space ! If an atom were expanded to the size of a stadium, the nucleus would be the size of a pea at the centre of the pitch. Every atom has: mass number • A symbol 9 • An atomic number • A mass number atomic number Be 4 symbol Rule The atomic number is the number of 2 protons in the nucleus. This is what gives an atom its identity. A phosphorus atom is a phosphorus atom and not a sulphur atom because it contains 15 protons, not 16. Rule The mass number is the total number of 3 protons + neutrons in the nucleus These are what give an atom its mass.
