* Atoms are neutral: They have an equal number of protons (positively charged) and electrons (negatively charged).

* Ions form by gaining or losing electrons:

* Cations: An atom that loses electrons becomes a cation (positively charged).

* Anions: An atom that gains electrons becomes an anion (negatively charged).

Examples:

* Sodium (Na) loses one electron to become a sodium ion (Na+), giving away an electron.

* Chlorine (Cl) gains one electron to become a chloride ion (Cl-), receiving an electron.

So, the answer to your question depends on the specific ion:

* Cations give away electrons.

* Anions receive electrons.
