Metals have s orbitals filled in their valence shells. This makes 1 or 2 valence electrons. Some metals gain configurations between the s and d orbitals. Non metals have s and p valence electrons, so they have 2 in s orbitals and up to 6 in p orbitals.
Metals tend to be on the left of the transition elements and therefore they have less valence electrons in their outer shell. Nonmetals are on the the right of the transition metals and those nonmetals almost have in their electron outer shell full and the number they have in the outer shell represents the valence electrons.
All atoms are in their lowest energy state when they have eight valence electrons like the noble gases. Metals contain fewer electrons in their outer shell and tend to form cations to have a noble gas configuration of electrons. Nonmetals contain more electrons and form anions to gain 8 valence electrons.
There must be a different reason but one reason is a large portion of metals are d-block element and d-block elements can have a lot valence states because of the fact that the 3d shell have similar energies and not large differences and that some have a lot of space in the d 3d orbital. There are no non-metals in the d-block catogory , so this obviously will add to the reason. Like i said there must be other reasons also.
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.
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
;need the same number of electrons to fill their valece shells ;have the same number of valence electrons
Strontium has 2 valence electrons because it is part of the Alkaline Earth Metals or Group 2 of the periodic table which all have 2 valence electrons
Valence electrons are the electrons present in the outermost shell of an atom.You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.

Nonmetal atoms are the atoms that borrow electrons. The number of atoms that can be borrowed or lent are what's known as valence.
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
-4 for nonmetals and +4 for metals
greater conductivity and higher melting points than nonmetals. Or D, because your looking at the STAR review packet. :)
Group 1 (alkali metals): Na(+1), Li (+1)Group 17 (halogens): Cl(-1), Br(-1)
Alkali Earth metals have a single valence electron, and are found in the first group.
Alkaline earth metals are group 2 elements and have 2 valence electrons.
