Is Calcium a Metal, Nonmetal or Metalloid?
Calcium (Ca) is a metal — a reactive metal of group 2 with two valence electrons ready to bond. It sits in group 2, period 4, and is a solid at room temperature.
Teachers call it "one fact, fully handled" — exactly what this page does for Calcium. 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
Calcium is a metal. Chemists decide by behaviour, not appearance: metals (like Calcium) give up electrons, shine when freshly cut, and conduct heat and electricity; nonmetals take or share electrons and (as solids) break rather than bend. Calcium checks every metal box — placed in the alkaline earth metal family of the table.

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