What else can I help you with?
Do all nonmetals have a completelyfull Valence shell of electrons?
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.
The valence electrons found in metals are different from nonmetals because .?
metals can conduct electricity, the valence electrons of nonmetals cannot roam freely
What will a non-metal do with its valence electrons?
Nonmetals attract electrons.
When nonmetals react with other nonmetals the atoms of nonmetals do what with electrons?
Share
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals can gain electrons to fill their valence shells. By doing so, they can achieve a stable electron configuration, usually by reaching a full outer shell of electrons (usually 8 electrons, except for hydrogen and helium which only need 2 electrons).
What group is mostly nonmetals and has 7 valence electrons?
Halogens.
Chemical property of non metals?
Non metals are elements that are not metals such as iron, and silver. They usually have four to eight electrons in their outer shell, gain or share valence electrons easily and form oxides that are acidic.
How valence electrons can atoms of nonmetals have?
always more than 4
In a reaction how many valence electrons will probably gain two electrons or share two covalent bonds?
In a reaction u need two valence electrons to gain or share two valence electrons.
Do nonmetals become more reactive when they move left to right?
Yes. This is due to the fact that their valence shells are adding electrons, coming closer to having an octet. The halogens in group 17/VIIA are the most reactive nonmetals because they have seven valence electrons and readily react in order gain the eighth valence electron, which gives them an octet like the nearest noble gas. It takes much less energy to gain one electron or share one electron, than it does to gain or share two or more electrons.
What time describes the most reactive nonmetals that have seven valence electrons?
Halogens
How many valence electrons can atom of nonmetals have?
always more than 4
