Solution 1

To answer this question, we need to look at the electron configuration of each atom.

  1. Mg (Magnesium) - [Ne] 3s². All electrons are paired.
  2. S (Sulfur) - [Ne] 3s² 3p⁴. There are two unpaired electrons in the 3p orbital.
  3. Ga (Gallium) - [Ar] 3d¹⁰ 4s² 4p¹. There is one unpaired electron in the Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
