Write Lewis structure of the following compounds and show format charge on each atom.
`HNO_(3), NO_(2), H_(2)SO_(4)`

Explanation

The Lewis structure of the following compounds and formal charge on each atom are as
i) `HNO_(3)`

Formal charge on an atom in a lewis structure = (total number of valence electrons in free atom]-[total number of non-bonding (lone pairs) electrons]-`1/2` [total number of bonding or shared electrons]
Formal charge on H=`-0-1/2xx2=0`
formal charge on N`=5-0xx1/2xx8=1`
Formal charge on O(1) = `6-4-1/2xx4=0`
Formal charge on O(2) = `6-4-1/2xx4=0`
Formal charge on O(3) =`6-6-1/2xx2=-1`
ii) `NO_(2)`

Formal charge on O(1) = `6-4-1/2xx4=0`
Formal chage on N=`5-1-1/2xx6=+1`
Formal charge on O(2) = `6-6-1/2xx2=-1`
iii) `H_(2)SO_(4)`

Formal charge on H(1) or H(2)=`1-0-1/2xx2=0`
Formal charge on O(1) or O(3) =`6-4-1/2xx4=0`
Formal charge on O(2) or O(4) = `6-6-1/2xx2=-1`
Formal charge on S=`6-0-1/2xx8=+2`
