Atomic Structure

Mass number

The number of protons + the number of neutrons

Atomic number

The number of protons or electrons in an atom

Isotopes

Atoms of the same element with different atomic mass

Due to differing numbers of neutrons

Ions

Are charged particles

Negative: - Anions

Gained electrons

Positive: - Cations

Lost electrons

Are formed when atoms gain or lose electrons
