DOK Level 1: Recall

Explain how the number of protons and electrons in an atom determines its charge.

• If the number of protons equals the number of electrons, the atom is neutral.

• If the number of protons is greater than the number of electrons, the atom is negatively charged.

• If the number of electrons is greater than the number of protons, the atom is positively charged.

• The charge of an atom is independent of the number of protons and electrons.
