Answer

Brief Explanations:

  1. For the compound (K_3N), the correct IUPAC name is potassium nitride. The prefix "tri -" is not used in the IUPAC naming of simple ionic compounds when the cation is a main - group metal in its common oxidation state. Potassium ((K)) has a + 1 charge and nitride ((N^{3 -})) has a - 3 charge, and the formula (K_3N) is the result of charge - balancing.
  2. For lead(II) nitrate, lead has a + 2 charge ((Pb^{2+})) and the nitrate ion has a - 1 charge ((NO_3^{-})). To balance the charges, two nitrate ions are needed for each lead ion, so the formula is (Pb(NO_3)_2).

Answer:

  1. False
  2. A. (Pb(NO_3)_2)
