Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom.
The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (ml), and the spin quantum number (ms) have strict rules which govern the possible values.
Identity allowable combinations of quantum numbers for an electron. Select all that apply.
a) n = 3, l = 2, ml = −2, ms = −1/2
b) n = 4, l = 0, ml = 1, ms = −1/2
c) n = 3, l = −2, ml = −2, ms = +1/2
d) n = 5, l = 4, ml = 4, ms = +1/2
e) n = 3, l = 3, ml = 1, ms = +1/2
f) n = 2, l = 1, ml = 0 ,ms = 0

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
