Electrons, protons, and neutrons.

Explanation:

Electrons (represented by a -) have a negative charge. If the charge of an atom is negative, that means there are more electrons present.

Protons (represented by a +) have a positive charge. If the charge of an atom is positive, that means there are more protons present.

Neutrons (not usually represented by anything, but sometimes referred to as a 0, meaning there is an equal charge) have a neutral charge. If the charge of an atom is neutral, that means that the number of protons and electrons present balance each other out.
