<reasoning>

Identify the compound type

Using the Covalent Bonding knowledge point

• \(\text{PN}_3\) contains phosphorus (\(\text{P}\)) and nitrogen (\(\text{N}\)).
• Both elements are nonmetals.
• Nonmetals share electrons to form covalent bonds.

Determine the chemical name

Using the Chemical Nomenclature knowledge point

• First element: phosphorus (no prefix needed for a single first atom).
• Second element: nitrogen, changed to "nitride" with prefix "tri-" for three atoms.
• Full name: phosphorus trinitride.

</reasoning>

<answer>
A. This is a covalent compound because both phosphorus (P) and nitrogen (N) are nonmetals, which share electrons to form covalent bonds.

B. To name this covalent compound:

1. Name the first element: phosphorus.
2. Name the second element with an "-ide" suffix: nitride.
3. Add a Greek prefix to indicate the number of atoms of the second element (3 atoms = "tri-"): trinitride.

The correct name is phosphorus trinitride.
