A
A cation has a negative charge, while an anion has a positive charge.
B
Cations and anions are both formed by gaining electrons.

Verified step by step guidance1
Step 1: Understand the definitions of ions. An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net electrical charge.
Step 2: Recall that a cation is formed when an atom loses electrons, which results in a positive charge because there are more protons than electrons.
Step 3: Recall that an anion is formed when an atom gains electrons, which results in a negative charge because there are more electrons than protons.
Step 4: Compare the charges: cations have positive charges, and anions have negative charges.
Step 5: Use this understanding to evaluate the given options and identify that the correct description is: 'A cation has a positive charge, while an anion has a negative charge.'
