Is Nihonium a Metal, Nonmetal or Metalloid?
Nihonium (Nh) is a metal — a real metal — softer and lower-melting than the transition metals, but still lustrous and conductive. It sits in group 13, period 7, and is a solid at room temperature.
Teachers call it "one fact, fully handled" — exactly what this page does for Nihonium. The answer sits at the top in bold; scroll for the working, the shell-by-shell breakdown and the two questions students ask most.

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

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