Question

1. choose the best answer based on the lewis structure.

what is the central atom?
oxygen
hydrogen

Explanation:

In the Lewis structure shown, the oxygen atom is in the center, bonded to two hydrogen atoms. Hydrogen atoms are typically terminal (not central) in such structures due to their valency (can form only one bond), while oxygen, with its ability to form multiple bonds and having lone pairs, is the central atom here.

Answer:

oxygen
