Answer:

The IE values for Si and S are lower than P

Explanation:

Because Si belongs 4A group where as P belongs to 5A group so Atomic size of Si is bigger than P.

In sulfur, the 4 electrons in the 3p level, are all paired. While in phosphorus there are 2 paired electrons and 1 lone electron in the 3p level. Therefore, the first ionisation energy for sulfur will be slightly lower than that of phosphorus, due to the paired electrons in its 3p sub-level.
