Dear Student,

For 20782Pb, No  of electrons = No
 of protons = Atomic number=82Number of neutrons = Mass number - Atomic number                                     =207-82                                     =125Its electronic configuration will be [Xe] 4f14 5d10 6s2 6p2Number of valence electrons =4Its valency is 2

how many electrons protons and neutrons are present in 207Pb82.write its electronic configuration. how many Valence Electrons does it have ?what will be its valency?
