(A) The formula for calculating the formal charge is: $	ext{Formal charge} = [	ext{Total number of valence electrons in free state}] - [	ext{Total number of lone pair electrons}] - \frac{1}{2} [	ext{Number of bonding electrons on that particular atom}]$ For the $N$ atom in $NH_4^{+}$: - The number of valence electrons in a free $N$ atom is $5$. - The number of lone pair electrons on the $N$ atom is $0$. - The number of bonding electrons around the $N$ atom is $8$ (since there are $4$ covalent bonds). $	ext{Formal charge on } N = 5 - 0 - \frac{1}{2} 	imes 8 = 5 - 4 = +1$.
