: O :: O : O :

A. The atom in the middle is the central atom, holding the other atoms around it. so obviously the No 1 atom.
B. Other atoms are then accordingly numbered.
C. Formal charge = V(Total valencw e) - 1/2 S(shared e) - L(left off unshared e).
For O 1 : 6 - 1/2 (6) - 2 = 1.
For O 2 : 6 - 1/2 (4) - 4 = 0.
For O 3 : 6 - 1/2 (2) - 6 = - 1
