The electron configuration [Xe] 6s2 4f14 5d10 6p2 gives the configuration of element lead . option C is correct.
The electronic configuration is the system in chemistry based on which the filling of electrons takes place in the orbitals of s, p,d, and f orbitals according to their atomic numbers.
For example, if the element is in the 4th number of the periodic table then its electronic configuration will be 1s2 2s2 that is 4 electrons are filled in the space of the s orbital.
Like this there is a fixed common electronic configuration for all the elements present in the periodic table this specifies many things about the stability and reactivity of the elements 6s and 6p are the electrons present in the valance shell .
Therefore, the given electronic configuration is of element lead. option C is correct.
