What is the electronic configuration of sulfur?

At. At.

No. No. Capacity = 2

No. No. Capacity = 8

No. No. Capacityis 8.

1st orbit only has 1s orbital. Electronic configuration is therefore 1s2

2nd orbit contains 2s and 2p orbitals. We know that s orbital can hold maximum. 2 electrons, and p orbital may hold max. 6 electrons, so the configuration is 2s2 and 2p6

The 3rd orbit contains 3s, 3p, and 3d orbitals. According to Aufbau’s rule, Energy of 3s = Energy of 3p = Energy of3d. Therefore, 3s is filled first and then 3p and 3. Electronic configuration is therefore 3s2/3p4. Because all electrons can be accommodated in 3p, 3d will also remain empty. In 3p orbitals, all 3 degenerated orbitals receive 1 electron at the beginning and then pairing follows Hunds’ rule.

The final electronic configuration for Sulphur is thus

1s2 2s2 2p6 3s2 3p4
