This atom could be any of a number of different elements: having 8 valance electrons does not necessarily mean that the outer shell of the atom is full as larger atoms can store more electrons per shell (first shell=2, 2nd=8, 3rd, 18, etc)
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
CH3CO-OH (acetic acid) has 10 valence electrons. The carbon atom contributes 4 valence electrons, each hydrogen atom contributes 1 valence electron, and the oxygen atom contributes 6 valence electrons.
A neutral atom of fluorine contains 7 valence electrons.
The outer shell of an atom is the valence shell, which contains the valence electrons.
