Concept explainers
a.
To determine:
The number of valence electrons present in
Introduction:
In a molecular or atomic orbital the electrons of an atom or molecule are distributed. This distribution of electrons is known as the electronic configuration of the atom or molecule. It is used to show the orbitals of an atom in its ground state. The valance electrons are those which are present in the outermost principle energy level.
