Is Hafnium a Metal, Nonmetal or Metalloid?
Hafnium (Hf) is a metal — a typical hard metal: lustrous, malleable, an excellent conductor, and famous for colourful compounds and variable valency. It sits in group 4, period 6, and is a solid at room temperature.

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

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