Want this question answered?
There are 2 valence electrons in an atom of magnesium. There are 5 valence electrons that are in an atom of phosphorus. There are 4 valence electrons that are in a silicon atom.
The electrons farthest away from the nucleus are the valence electrons of an atom.
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Valence electrons
Valence electrons are those in the outermost shell of the atom.
There are 8 Valence Electrons.
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
A chlorine atom has 7 valence electrons.
Neutral atoms have the same number of electrons as protons. Therefore, the number of electrons in any atom of one element is the same as its atomic number on the periodic table. Krypton is number 36, so it has 36 electrons total.As a noble gas, it has 8 outer-shell (valence) electrons.
A neutral atom of oxygen would have 6 valence electrons.
I do not think that Bromine behaves like Krypton in chemical reactions. Krypton is very unreactive due to the fact that it has a full stable set of valence electrons, and Bromine is extremly reactive and has high electronegativity because is does not have a full stable set of valence electrons. Although, I do suppose that if a Bromine atom were to become a negative ion (Br+1) by gaining another electron, it would act as if it were a Krypton atom.
