Question

most of the__ and some main - group metals can form two or more cations with different charges. group 1 metals nonmetal group 2 metals transition metals question 9 1 pts when naming an ionic compound containing a metal cation with a variable charge, a(n)__ in parenthesis is used to specify the charge on cation. arabic numeral roman numeral binary number hexadecimal number

Explanation:

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
