In the context of naming binary molecular compounds, what is the correct name of the compound $N{H}_3$?

Apply the naming rules: 'Nitrogen trihydride' follows the binary molecular compound naming convention, where 'tri-' indicates three hydrogens and 'hydride' indicates hydrogen as the second element.

Recognize that NH₃ is a common compound with a well-known common name: ammonia, which is used instead of the systematic binary name.
