What are ions with a positive electrical charge considered to be?

Ions with positive charge are called cations.

Cations are positively charged ions that seek negative charge (electrons). Anions are negatively charged ions that seek positive charge. Because cations and anions seeks a charge opposite to theirs, they usually readily bond to one another.

Tip: Remember that cations are the ones with positive charge like this pun: CATions are PAWSitive.
