Sulfur: every subshell, one by one
The table below unpacks [Ne] 3s^2 3p^4 line by line, so you can watch Sulfur's 16 electrons take their seats in order of increasing energy.
| Subshell | Electrons | Total so far |
|---|---|---|
| [Ne] | 0 | 10 |
| 3s | 2 | 12 |
| 3p | 4 | 16 |
Electrons per shell (K, L, M…)
Grouped by principal quantum number instead of subshell, Sulfur carries 2 in shell 1, 8 in shell 2, 6 in shell 3. The outermost shell holds 6 electrons — the ones that do all the bonding.
How to derive it yourself
Follow the aufbau order (1s → 2s → 2p → 3s → 3p → 4s → 3d → …), pouring 16 electrons into orbitals of capacity 2 (s), 6 (p), 10 (d) and 14 (f) until none remain. Write the filled inner shells as the nearest noble-gas core — for Sulfur that gives [Ne] 3s^2 3p^4.

How many electron shells does Sulfur have?
Sulfur is in period 3, so its electrons occupy 3 shells, holding 2, 8, 6 electrons respectively.
How many valence electrons does Sulfur have?
Its outermost shell holds 6 electrons, so Sulfur has 6 valence electrons that take part in bonding.
What is the noble-gas shorthand for Sulfur?
The shorthand form is exactly [Ne] 3s^2 3p^4.
