protons and electrons.

Electrons, represented by (-), have a negative charge.

Neutrons, represented by (0), have no charge.

Any number of neutrons you have, they don't affect the charge.

If you have more protons than electrons, the charge will be positive.

If you have more electrons than protons, the charge will be negative.

When you have an equal number of the two, the charge is neutral.
