Question

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

what is the central atom?
hydrogen
oxygen

Explanation:

In a Lewis structure, the central atom is the one that is bonded to multiple other atoms. In the given Lewis structure of \(H_2O\) (water), the oxygen atom (\(O\)) is bonded to two hydrogen atoms (\(H\)). Hydrogen atoms can only form one bond each, so they cannot be the central atom. The oxygen atom, which can form two bonds, is the central atom in this structure.

Answer:

oxygen
