Question

write the name of the following covalent compound: ncl₃

Explanation:

Step1: Identify the elements

The compound \( \text{NCl}_3 \) consists of nitrogen (N) and chlorine (Cl).

Step2: Use prefixes for covalent compounds

For covalent compounds, we use prefixes to indicate the number of atoms. The prefix for 1 (when the first element has 1 atom) is "mono-" but it is often omitted for the first element. For 3 atoms, the prefix is "tri-".

So, nitrogen (with 1 atom, so no prefix) and chlorine (with 3 atoms, so "tri-") followed by the root of the element name and "-ide".

Answer:

Nitrogen trichloride
