Question

multiple choice question
most transition metals and group 13 and 14 metals have ______.

one common ion with a charge of 3+
more than one possible ionic charge
one common ion with a charge of 1+
one common ion with a charge of 2+

Explanation:

Transition metals and group 13/14 metals often have partially filled d or f orbitals, allowing them to lose varying numbers of electrons, resulting in multiple possible ionic charges. For example, iron can form Fe²⁺ and Fe³⁺, and tin can form Sn²⁺ and Sn⁴⁺. The other options describe fixed charges that do not apply to most of these metals.

Answer:

more than one possible ionic charge
