Question

What is the ground state electronic configuration of $Pb$ ?

Answer 1

Hint :We know that $Pb$ means lead. Lead is a soft, silvery white or grayish metal in group 14 of the periodic table. The ground state electronic configuration is the arrangement of electrons around the nucleus of an atom with lower energy levels.

Complete Step By Step Answer:
We have $Pb$ , That is lead. We know that the atomic number of lead is 82. This means that all atoms of lead have 82 protons in their nuclei. In a neutral lead atom, there will also be 82 electrons in the electron cloud.
The ground state electronic configuration of $Pb$ is the same as the regular configuration in which the electrons are in lowest possible energy state.
The ground state electron configuration of $Pb$ is
 $[Xe]4f^{14}5d^{10}6s^{2}6p^2$ .
Here $[Xe]$ is a Noble gas Xenon and the atomic number is 54.

Note :
Lead is very malleable, ductile and dense and is a poor conductor of electricity. Molten lead is an excellent solvent and collector for elemental silver and gold. The structural applications of lead are limited by its low tensile and fatigue strengths and its tendency to flow even when only lightly loaded.
