Is Plutonium a Metal, Nonmetal or Metalloid?
Plutonium (Pu) is a metal (an actinide) — an actinide — a radioactive f-block metal of period 7. It sits in the f-block, period 7, and is a solid at room temperature.

The one-line answer, with reasons
Plutonium is a metal (an actinide). Chemists decide by behaviour, not appearance: metals (like Plutonium) give up electrons, shine when freshly cut, and conduct heat and electricity; nonmetals take or share electrons and (as solids) break rather than bend. Plutonium checks every metal box — placed in the actinide family of the table.

Students also ask
Is Plutonium a good conductor of electricity?
Yes — like other metals, Plutonium conducts electricity and heat well, thanks to its sea of free electrons.
Can a gas be a metal — like Plutonium?
Yes — being a metal or nonmetal is about bonding and electron behaviour, not state. At room temperature Plutonium is a solid, and that says nothing against its metallic character.
