Determine the number of bonding electrons and the number of nonbonding electrons in the structure of OF2

Question

Enter the number of bonding electrons followed by the number of nonbonding electrons in the dot structure of this molecule separated by a comma (e.g., 1,2).

Answer 1

The Lewis structure for OF2 shows that there are 4 electrons involved in covalent bonds. As there are a total of 20 electrons among the three atoms, this would mean there are 16 non- bonding valence electrons.

The answer should be (4,16)
