What is the name of the Pb2+ ion?
Lead donates them, so you have a Lead (II) ions. This is a correct choice. Pb2O * Oxygen still wants 2 electrons and gets them from the lead.
If the elements in Group 4 form 2+ ions, they lose their p electrons, leaving the s2 pair unused. For example, to form a lead(II) ion, lead loses its two 6p electrons, but the 6s electrons are left unchanged, an “inert pair”. Ionization energies usually decrease down a group as electrons get further from the nucleus.
