greater conductivity and higher melting points
than nonmetals. Or D, because your looking at the STAR review packet. :)
Usually, metallic elements have a lower number of valence electrons with respect to the non metal elements in the same period.
I have a question, what website is the chem STAR review packet on?
smaller
Yes, nonmetals generally gain electrons to fill valence shells.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.
8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
Generally, a compete valence shell holds EIGHT electrons.
Yes, nonmetals generally gain electrons to fill valence shells.
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.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
Nonmetals attract electrons.
Non-metal atoms gain an electron, or electrons, from another atom to become negatively charged ions.
Halogens.
Nonmetals because they have a lot of valence electrons.
Yes, they share them in a covalent bond.
always more than 4
always more than 4
