Respuesta :
Lead (Pb) has the electron configuration [xe] 6s2 4f14 5d10 6p2.
What is electronic configuration ?
A neutral element's total number of electrons is represented by its electronic configuration. To get the total number of electrons in an atom, we sum all the superscripts.
As the last electron enters the p orbital, the provided element is a p block element. Xenon, a noble gas with 54 electrons, is the closest.
According to Afbau's rule, the electrons are filled in the sequence of increasing energies, and the electronic configuration in terms of the noble gs configuration is as follows:
Total electrons = 54 + 2 + 14 + 10 + 2 = 82
Lead is the element with the symbol whose atomic number is 82 since it contains 82 electrons.
