6 valence electrons
6 valence electrons 1s2 2s2 2p4 These 6 valence electrons are in the outer shell.
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )
The family containing 7 valance electrons is called the Halogens. They are all called (in order of increasing valance electrons): Alkali Metals(1), Alkaline Earth Metals(2), Boron Group(3), Carbon Group(4), Nitrogen Group(5), Oxygen Group/Chalcogens(6), Halogens(7), and Noble Gasses(8/full).
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons

6 Use the periodic table as a guide. As you go across from left to right the number of valence electrons increases. H = 1 Be = 2 B = 3 C = 4 N = 5 O = 6 F = 7 This trend stays the same all the way down each column. Usually periodic tables are marked on the top with roman numerals or something to signify how many valence electrons each element has.

it has 6 valance electrons, the number of electrons can be determined by the number of protons it has, which is the same as it's atomic number.
