Our upcoming test on 12/24 is on the following
FOR 8H:
You need to know:
1. Why atoms do not normally have an electrical charge
2. Why the periodic table is laid out the way it is laid out
3. How to figure out where the most reactive elements are
4. How to find the atomic mass of an element off the periodic table
5. The families of the periodic table
6. Which elements never react and why
7. How to find the number of protons off the periodic table
8. How to draw the atomic diagram (the atomic structure)
9. How to draw the electron dot diagram
10. Why valence electrons are important
11. How valence electrons help in all types of bonding
12. What an ionic bond is
13. How to find the charges of ions off of the periodic table
14. The names of polyatomic atoms (gotten off the common ion list)
15. How to write chemical formulas for both ionic and covalent bonds
16. How to write the names of both ionic and covalent bonds
FOR 8R:
1. How to figure out the # of protons from the atomic number
2. Know where the parts of the atom are found (electrons, protons and neutrons only)
3. What an isotope is
4. Where very reactive GASSES are on the periodic table
5. Know how the periodic table is laid out
6. Know how to use the periodic table (period 5, group 3, etc.)
7. Know the names of the families
8. Know the names of the regions on the periodic table
9. Be able to explain why oxygen becomes more stable after it bonds and forms compounds
10. Be able to explain why elements are reactive and be able to explain why, in terms of valence electrons, alkali metals are more reactive than Halogens
11. Be able to explain the difference between covalent, ionic and metallic bonds
12. Know how to draw the atomic structure and the electron dot diagram/lewis structure of an element
13. Be able to explain how to find the # of valence electrons from the periodic table
14. Know the names of the polyatomic atoms (NO3, PO4,, HCO3, CO3)
15. Know how to write the chemical formula of ionic compounds
16. Know how to write the name of ionic compounds from the formula

Ammonium=NH4
Nitrate= NO3
Carbonate= CO3
Sulfate= SO4
Phosphate=PO4
Bicarbonate= HCO3
