Pb2+ has lost two electrons, so it has 82 - 2 = 80 electrons.

How many electrons does an atom of lead have if it is positively charged?

Lead forms the Pb2+ ion, as lead has an atomic number of 82, the Pb2+ ion has 80 electrons in total


The pb k-egde xanes data reveals that pb is in a mixed valence state of pb4 plus and pb2 plus however in literature pb is claimed to be in pb2 plus state the pb 6s2 electrons hybridize with the o 2p?

The Pb K-egde Xanes data reveals that Pb is in a mixed valence state of Pb4+ and Pb2+. However in literature Pb is claimed to be in Pb2+ state. The Pb 6s2 electrons hybridize with the O 2p electrons to form strong covalent bonding which results in the relative displacement of Pb cage with respect to the O-octahedron. This results in increase ferroelectric properties of PbTiO3.However the question is that in the covalent state of the Pb2+ will it appear as Pb4+ state in the Pb K-edge? The reason argued here is that the Pb will lose the 6s2 electrons to form the bond and hence appear to be Pb4+. Hence the argument placed by this pool of thought is from the EXAFS data what appears to be Pb4+ is actually the covalently bonded Pb2+ while what appears to be Pb2+ is actually the ionic type Pb2+.What is the oxidation state of Pb and Ti in PbTiO3 ?


Why Pb2 plus is more stable than Pb4 plus?

Pb2+ is more stable than Pb4+ because the 6s and 6p orbitals in Pb have poor shielding ability, making it energetically unfavorable for Pb to lose 4 electrons and achieve the 4+ oxidation state. The higher charge of Pb4+ leads to greater electron-electron repulsions, making it less stable than Pb2+.


Pb2 plus yields Pb4 plus is this oxidation or reduction?

This is oxidation. The Pb ion is going from a +2 oxidation state to a +4 oxidation state, which means it is losing electrons and being oxidized.


What is the ion with 82 protons and 80 electrons?

The ion with 82 protons and 80 electrons is a doubly charged ion of lead (Pb2+). The presence of 80 electrons instead of the expected 82 results in a net positive charge of 2, indicating that 2 electrons have been lost.
