Is Phosphorus a Metal, Nonmetal or Metalloid?
Phosphorus (P) is a nonmetal — a nonmetal: a poor conductor, hungry for electrons, forming molecules or covalent networks rather than metallic crystals. It sits in group 15, period 3, and is a solid at room temperature.

The one-line answer, with reasons
Phosphorus is a nonmetal. Chemists decide by behaviour, not appearance: metals (unlike Phosphorus) give up electrons, shine when freshly cut, and conduct heat and electricity; nonmetals take or share electrons and (as solids) break rather than bend. Phosphorus follows the nonmetal playbook — placed in the nonmetal family of the table.

Students also ask
Is Phosphorus a good conductor of electricity?
No — Phosphorus is a nonmetal and does not conduct the way metals do.
Can a gas be a nonmetal — like Phosphorus?
Yes — being a metal or nonmetal is about bonding and electron behaviour, not state. At room temperature Phosphorus is a solid, and that says nothing against its nonmetallic character.
