Question

how many atoms of oxygen (o) are in the compound: *
water
h₂o
1 atom
2 atoms
3 atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula of water is \(H_2O\). In a chemical formula, the subscript indicates the number of atoms of an element. For oxygen (\(O\)) in \(H_2O\), there is no subscript written next to \(O\). When no subscript is present, it is understood to be 1. So, there is 1 atom of oxygen in one molecule of water.

Answer:

1 atom
