Step 1: Identify the total number of valence electrons in the molecule
The formate ion, CHO$^ {-2}$, consists of one carbon atom (4 valence electrons), one oxygen atom (6 valence electrons), and two hydrogen atoms (2 valence electrons each).
Additionally, there is a charge of - 2, which contributes 2 extra electrons. Therefore, the total number of valence electrons is:
Final Answer
The formate ion, CHO$^ {- 2}$, consists of one carbon atom (4 valence electrons), one oxygen atom (6 valence electrons), and two hydrogen atoms (2 valence electrons each).
