Interpretation:
The Lewis structure of the given compound
Concept Introduction:
Lewis structure:
The representation of valence shell electrons around the atom is known as Lewis structure or Lewis dot structure. Electrons are represented as a dot in Lewis structures, a single dot represents unpaired electron and paired of dots represents paired electrons.
