Aluminium, silicon, phosphorus, sulfur, chlorine and argon have the valence electrons (1 to 6 respectively) ending in 3p level
Its Phosphorus (P)
PS: NOT Al!
aluminum or gallium
I think that is Gallium.
Al
Phosphorus
Goup 5A
sulfur
1s2 2s2 2p6 3s2 3p 4s2
1s^2 2s^2 2p^6 3s^2 3p^2
The shorthand electron configuration of aluminum is: [Ne] 3s2 3p1
it is 1s(2) 2s(2) 2p(6) 3s(2) 3p(4)
The electron configuration of argon is [Ne]3s23p6.
1s2 2s2 2p6 3s2 3p 4s2
Nitrogen's symbol is N. Its electron configuration is 2s, 3p.
Chlorine Electron configuration - [Ne] 3s 2 3p 5
It would be potassium (K). Its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1.
Sulfur
Al, Si, P, S, Cl and Ar have 1, 2, 3, 4, 5 and 6 electrons respectively in the 3p (valence orbitals). However all elements after Argon have completely filled 3p orbitals though 3p is not the valence orbital.
Long-hand version: 1s^2 2s^2 2p^6 3s^2 3p^1 Short-hand version: [Ne] 3s^2 3p^1 Note: The "^" symbol means the the following number is in the form of a superscript.
1s^2 2s^2 2p^6 3s^2 3p^2
The shorthand electron configuration of aluminum is: [Ne] 3s2 3p1
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
1s 2s 2p 3s 3p 4s 3d 2p
it is 1s(2) 2s(2) 2p(6) 3s(2) 3p(4)
