Answer 1

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.

Here's why:

1. Neutral Atoms: A neutral atom of lead (atomic number 82) must have 82 protons and, to remain neutral, it must also have 82 electrons.

2. Ions: Ions are atoms that have gained or lost electrons. Therefore, a lead ion (including both cations and anions) can have a different number of electrons than protons. However, all lead ions will still have 82 protons, since the atomic number defines the element.

The other statements are incorrect because they claim that ions must also have 82 electrons or 82 protons, which is not true for ions.
