What name is given to a chemical element that cannot be classified either as a metal or a non-metal?

I have missed my teachers in Chemistry (High School and College)

I don't believe all metals are magnetic, are they?

O, MIT researchers have observed magnetism in an atomic gas of lithium cooled down to 150 millionths of a degree above absolute zero. This experiment represents a point of unification between condensed matter research and the field of atomic science and lasers, and could influence areas such as data storage and medical diagnostics.

samisha, all metals and non metals are not metalloids. there is a difference between three of them

Metalloids come in group 14 of periodic table and have four electrons in valence shells.

all metals and non metals are metalloid I know this ...

I think not allme

no all metals aren't magnetic

FearsomeFlyer2654, Do gasses have metallic properties? I'm no expert but I've never seen a magnetic gas
