Magnesium Atom vs. Magnesium Ion: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Published on January 2, 2024
A magnesium atom is a neutral element with 12 protons and electrons, whereas a magnesium ion typically has a +2 charge due to the loss of two electrons.

Key Differences

A magnesium atom is the basic unit of the element magnesium, containing 12 protons and 12 electrons, making it electrically neutral. In contrast, a magnesium ion, specifically a Mg2+ ion, is formed when a magnesium atom loses two electrons, resulting in a positively charged species with 12 protons and only 10 electrons.

In terms of chemical behavior, a magnesium atom can participate in reactions as a neutral entity, often involved in forming compounds. The magnesium ion, however, being positively charged, readily interacts with negatively charged ions to form ionic compounds, a common example being magnesium chloride (MgCl2).
