(a)
Interpretation:Name of element from below valence electron diagram should be identified.
Concept introduction:The process by which electrons are distributed in molecular or atomic orbitals is termed as electronic configuration. Hund’s rule of multiplicity states that electrons are filled singly in an orbital initially and then pairing occurs with different spin. Thus atomic orbital is filled in accordance to this rule.
Valence electron defines the group of the element. Energy, size, shape, and orientation of atomic orbital are determined with help of some numbers. These numbers are called quantum numbers. Principal quantum number is represented by
