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.
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
always more than 4
when nonmetals bond with nonmetals they form covalent bonds by sharing their valence electrons
Nonmetals attract electrons.
The more to the right of the periodic table the more reactive Only for nonmetals, for metals the most reactive are to the left and have 1 valence electron. Nonmetals have many, 6 or 7, valence electrons that make them very reactive.
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.
Nonmetals become stable by gaining or sharing enough valence electrons to have a set of eight valence electrons in a shell or energy level
Oxygen is the only nonmetal with 6 Valence Electrons in period 2.
Yes, they share them in a covalent bond.
Metals transfer their electrons to nonmetals in order to reach the "octet" or 8 electrons in the valence shell.
nonmetals form negative ions (i.e. O^-2) by gaining valence electrons metals form positive ions (i.e. K^+1) by losing valence electrons
The nonmetals in Group 6A will gain two electrons because they have 6 electrons in their valence shell. The nonmetals in Group 7 will gain one electron.
Nonmetals because they have a lot of valence electrons.
Halogens such as chlorine, flourine, bromine, iodine
during a chemical reaction valence electrons are most always transferred
Yes, usually from 4 to 8 depending upon the element.
alkali earth metals
