b. how can you tell if an atom has a positive charge? what type of ion is this?

Explanation:

1. An ion is an atom or a group of atoms that has gained or lost one or more electrons, resulting in a net electric charge.
2. a. An atom has a negative charge when it has more electrons than protons. This type of ion is called an anion.

b. An atom has a positive charge when it has fewer electrons than protons. This type of ion is called a cation.
