Question

24 2+ mg 12 the substance displayed is a cation negative ion neutral atom anion

Explanation:

To determine the type of the substance (Mg²⁺), we recall ion definitions: A cation is a positively charged ion (loses electrons), an anion is negatively charged (gains electrons), and a neutral atom has no charge. Mg²⁺ has a 2+ charge, so it is a cation (positive ion). "Negative Ion" and "Anion" are incorrect (they are negative), and "Neutral atom" is incorrect (no charge).

Answer:

A. Cation
