no, but there are metalloids, which have properties of both metals and non metals
Yes if it has some of the same characteristics of metals but also the same as non metals, then it is a metalloid.
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
