The correct statement that describes all neutral atoms and ions of lead is:
Neutral atoms of lead must have 82 protons, but ions can have more or fewer.
This is because all neutral atoms of lead (which is indicated by the atomic number of 82) have 82 protons and the same number of electrons, thus they are neutral. However, ions of lead can either lose or gain electrons, which means they can have more or fewer electrons than protons while still maintaining 82 protons.
