BEGINNING OF CHEMISTRY
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
(a) What is the atomic number>
(b) What is the atomic mass?
(c) Are the electrons equal to neutrons? protons?
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
(a)
(b)
(c)
(d)
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)
Problem 130
TOPIC:
Chemistry (pg 33-39)
Nitrogen (N) the most notable exception, can have any valence in its row (+5
–3, but never zero).
(a) 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?
