An energy sublevel refers to an electron orbital, which are designated as s, p, d or f. The maximum number of electrons in a p-type energy sublevel is 6.
In period 2 and hihger: 2p6 , 3p6 , 4p6 etc.
Six in total.
Per (3D)-direction 2 electrons: px2 , py2 , pz2
Since the p orbital has 3 sublevels, px, py and pz, and each can contain an unpaired electron, the total number of unpaired electrons in the 3p would be 3.
Since they are p orbitals, 6 electrons are occupied in the 3p orbital. there are 3 types of p orbital, px, py and pz
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.
18. 2 in the 3s, 6 in the 3p and 10 in the 3d.
A chromium ion has the atomic number 24. This means that a neutral atom has 24 electrons. Because it has the net charge of positive three, it has 21 electrons.

The maximum number of electrons in the 2p sublevel is 6. The p sublevel has three orbitals, each of which can take two electrons.

The max. number of electrons that can fill the 3s orbital is 2.
Since they are p orbitals, 6 electrons are occupied in the 3p orbital. there are 3 types of p orbital, px, py and pz
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.
The element with that electron configuration has 4 electrons in the third level. There are 2 electrons in the 3s sublevel and 2 more electrons in the 3p sublevel. This means 4 valence electrons total. This element is silicon (Si, #14).
the total electron distribution in such an atom is 1s--2 2s--2 2p--6 3s--2 3p--5 so, total number of electrons comes out to be 17. so, the element is chlorine. symbol is Cl.
18. 2 in the 3s, 6 in the 3p and 10 in the 3d.

3s^2 3p^6 3d^10 18 electron altogether in the third shell.
The element is sulfur (S, #16). [Ne] means neon is the nearest noble gas with a lower atomic number. The 3s23p4 means electrons have filled the 3s2 sublevel, and 4 out of 6 possible locations in the 3p sublevel are occupied. Adding the number of electrons to neon (2+4+10) gets you 16, which identifies the element. Sulfur is in period 3, which corresponds to the unfilled level of electrons. The group is 16(6A). Sulfur is considered a p-block element, because its valence electrons partially fill the p sublevel.
