Chapter 8 review
1. Chemical Bonds form by the attraction between a positive nucleus and negative electrons or the
the attraction between a positive ion and a negative ion.
2. They form to attain a noble gas configuration.
3. They are likely to from ions because the noble gases have to have a complete electron
configuration.
4. Ionization energy refers to how easily an atom loses an electron. Electron affinity indicates how
much attraction an atom has for an electron.
5. The formation of Ionic Bonds occurs when oppositely charged are force together. When two
metals for together, they usually are called salts.
6. Melting Point, Boiling Point and hardness. Melting point the the point of when metal melts at a
certain temperature. Boiling point is the point to where a metal/liquid boils at a certain
temperature. Hardness has to do with how easily a substance it scratched.
7. In order to be electrically neutral, the anions and cations must cancel each other out.
8. You need the formula unit to be able to write the correct chemical formula.
9. Subscripts are used for the bottom right number that represent the ions in each square of the
periodic table.
10. You have to look at the cations and anions and see if they cancel each other out, you have to look
look and see if they oxidize, monatomic ions are used to help name the compund and finally the
compound has an polyatomic, then it is named with the ion.
11. A metallic bond bond is the attraction of metallic cation for delocalized electrons. It is just like a
magnet attracting Nickel, Zinc or Iron.
12. In metallic bonding, the metals bond better when they are able to be drawn into thin sheets
(malleable) and if they are flexible or not (ductile).
13. Steel is coming from Iron and Brass being made from Copper.
14. Nobles gases are the few elements that do not like being able to bond with other elements.

16. Barium is a member of group 2A and it is a metal. It has 2 more electrons that a noble gas, and
the only thing that will really happen is if it loses 2 electrons, then it will have a positive ion.
17. The anion of Nitrogen forms when Nitrogen gains a electron(s).
18. Flourine has the higher reactivity. Neon is a noble gas, so it is not a very reactive element.
19. Potassium- High....FLourine- Medium....Neon-low reactivity.
20. Iron has multiple oxidation states. Therefore, when it is exposed to oxygen, it can easily gain an
electron or two.
