Question

Why sulfur has lower ionization energy than phosphorus?

Answer 1

Hi Friend♥♥♥

♦ In Sulphur two of the 3p electrons are paired .

♦There is some repulsion between the paired electrons in a same sub level

♦This reduces the force of attraction between the nucleus.

♦So less energy is required to remove it

This is the reason why sulfur had low ionization energy than phosphorus

Hope this helps u Friend♥♥♥
