Answer

Brief Explanations:

  1. Transition metals have variable oxidation states and can form two or more cations with different charges. Group 1 and group 2 metals have fixed oxidation states, and non - metals usually form anions.
  2. When naming ionic compounds with a metal cation of variable charge, Roman numerals in parentheses are used to indicate the charge on the cation. For example, FeCl₂ is iron(II) chloride and FeCl₃ is iron(III) chloride.

Answer:

  1. D. transition metals
  2. B. Roman numeral
