Concept explainers
a.
To determine:
The number of electron in outer energy level and the group number of lithium.
Introduction:
In the molecular or atomic orbitals the electrons of an atom or molecule is distributed. This distribution of electrons is called 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.
b.
To determine:
The number of electron in outer energy level and the group number of Silicon.
