Question

how many atoms of hydrogen (h) are in the compound?
ammonia
nh₃
1 atom
2 atoms
3 atoms
4 atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula of ammonia is \(NH_3\). In a chemical formula, the sub - script number next to an element symbol represents the number of atoms of that element in one molecule of the compound.

Step2: Determine the number of hydrogen atoms

For the formula \(NH_3\), the element hydrogen (\(H\)) has a sub - script of \(3\). This means that there are 3 atoms of hydrogen in one molecule of ammonia.

Answer:

C. 3 atoms
