For bonding between atoms we usually show the dot-cross diagram representing the outer most electrons of bonded atoms.
electron(Lewis) dot structures
6 valence electrons
six valence electrons
Eight - it has a full outer shell of electrons.
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 )
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
2 valance electrons
There are 27 valance electrons.
Iodine has 7 valance electrons
to fil the outermost energy level which is the level that contain all the valance electrons
The valance electrons.
8 valance electrons in valance shell means that atom is stable.
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
They have different numbers of valance electrons
2 valance electrons
Valance electrons are not located near the nucleus. These electrons are in fact located the furthest away from the nucleus compared to other electrons.
it was to gain 3 more valence electrons so it can be like the noble gases.
