Question

How many atoms are in ammonia?

Answer 1

Number of atoms present in Ammonia:

Step 1: The structure of ammonia contains one Nitrogen and three Hydrogen atoms, thus the molecular formula is ${\mathrm{NH}}_3$. So, there are four atoms in molecules of ammonia.

Step 2: The subscript number in the element indicates the number of atoms and an atom with no subscript is referred to be a single atom.

Hence, the molecule of ${\mathrm{NH}}_3$contains four atoms.
