Explain why sulfur deviates from the general trend in ionisation energies across period 3.

Sulfur has the electronic structure [Ne]3s2 3p4. This means there are 2 electrons in the same p orbital. These repel each other making it easier to remove the electron causing the ionisation energy to be lower than expected.
