Interpretation:
The element E in
Concept Introduction:
Second period has eight elements namely lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
Formal charge is a charge of each atom in the structure. A formal charge is the electric charge of an atom in a molecule. The sum of formal charges on neutral species must zero.
The sum of the formal charges on an ion must equal the charge on the ion. Most Lewis structures have values of zero for the formal charges of the atoms.
The formula to calculate formal charge on an atom is as follows:
