How many valence electron do atoms need to be staple?
8 valence electrons
How many additional valence electron does fluorine need to have a full valence shell?
ONE (apex)
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
How many electrons are in the outer energy level of a helium atom?
Helium and hydrogen and group 3 to 12 got 2 valence electron
How many valence electron do atoms need to be staple?
8 valence electrons
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 valence electron does phosphorous need to fill its outer shell?
3
How many additional valence electron does fluorine need to have a full valence shell?
ONE (apex)
How many electrons does potassium need to loss to get a full outer shell?
One, its only valence electron.
How many electrons does bromine need to fill its valence shell?
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
How many electrons are in the outer energy level of group 7 a elements?
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
How many additional valence electrons does chlorine need to have a full valence shell?
11 electrons makes the third energy level complete. One
How many additional valence electrons does fluorine need to have a full valence?
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 electrons does chlorine need to have a full outer shell?
1 additional electron will give chlorine 8 in the valence. You can see in the Periodic table, that Chlorine is next to Argon ( 1 to the left of it) so it needs 1 more electron to have the same configuration as Argon.
How many valence electrons need to be accommodated in the Lewis structure for LiCl?
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
