4. Problem 128 TOPIC: Chemistry (pg 33-39) Periodic Table Categorizations of Elements • Metalloids: boron (B), silicon (S), arsenic (As), germanium (Ge), antimony (Sb), tellurium (Te), and polonium (Po) • Metals: everything to the left of the metalloids • Nonmetals: everything that is not a metal • Noble or inert gases: column on the right • Halogens: column next to noble gases What is the atomic number> What is the atomic mass? Are the electrons equal to neutrons? protons?

5. Problem 129 TOPIC: Chemistry (pg 33-39) Oxidation (Valence) State Oxidation Number (oxidation state) • An electrical charge assigned by a set of prescribed rules. Elements have valence shells • Noble gases: completely filled shells (stable) • Non-noble elements: achieve a more stable shell by adding/losing electrons How does sodium reach a stable state with filled shells? How does oxygen reach a stable state with filled shells? How does aluminum reach a stable state with filled shells? How is Manganese different than (a) through (c)

6. Problem 130 TOPIC: Chemistry (pg 33-39) Nitrogen (N) the most notable exception, can have any valence in its row (+5 to –3, but never zero). Since nitrogen is diatomic (N2): how does it become stable? Some valence states to remember are: • hydrogen (H) column: +1 • beryllium (Be) column: +2 • boron (B) column: +3 • fluorine (F): –1 • oxygen (O): –2 Ionic compounds are based on the unequal sharing of electrons Covalent compounds are based on the sharing of electrons to become stable (b) How is methane (CH4) bonded?
