The Halogens.
There is no set amount of valence electrons for nonmetals. The amount of valence electrons a nonmetal has is determined by the number of electrons on the outer shell of the atom.
Yes, nonmetals generally gain electrons to fill valence shells.
No, lithium is ins a family of mostly metals with 1 valence electron.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
Nonmetals attract electrons.
The outer shell of an atom is most stable or non reactive with 8 electrons. 1 or 2 valence electrons would be reactive. It also would depend if it's bonded with another element.
Electrons are no reactive by itself but they are important in chemical reactions - valence electrons.
No, because metals are on the left side of the Periodic Table. Therefore, they are reactive. Nonmetals, on the left side of the Periodic Table, are less reactive, because they have more valence electrons.
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
