Noble gas

Is Oganesson a Metal, Nonmetal or Metalloid?

Quick answer

Oganesson (Og) is a nonmetal (a noble gas) — a noble gas — a nonmetal whose outer shell is already complete, so it hardly reacts with anyone. It sits in group 18, period 7, and is a gas at room temperature.

The one-line answer, with reasons

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

Students also ask

Is Oganesson a good conductor of electricity?

No — Oganesson is a nonmetal and does not conduct the way metals do.

Can a gas be a nonmetal — like Oganesson?

Yes — being a metal or nonmetal is about bonding and electron behaviour, not state. At room temperature Oganesson is a gas, and that says nothing against its nonmetallic character.
