Concept explainers
(a)
Interpretation:
The name of element with valence electron configuration
Concept introduction:
The electronic configuration is the ground state distribution of electrons among the orbital of species. The electronic configuration of an atom defines many chemical properties of an atom.
The number of electrons present in the highest occupied energy level is known as the valence electrons.
