How many additional valence electrons does fluorine need to have a full valence?
LqMartinezfb9459
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.
If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the Periodic Table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.

How many additional valence electron shells does bromine need to have a full valence shell?
It needs only 1 more electron since it already has 7 valence electrons.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
Number of valence electrons in chlorine?
I think that because chlorine has 17 electrons in all, and ten of them are filled up on the first two shells, then seven of them should be on the third shell, so seven of them are valance electrons.
What is the valence electron of argon?
Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)

How many valence electrons does oxygen need to have a full outer valence shell?
Oxygen is in group 16 so it has 6 valence electrons. In order to have a full outer shell, and satisfy the octet rule, it needs 2 more valence electrons to have a full outer shell.
