Question

The secoud ionisation energy sodium should be long then the secound ionisation energy magensium explain ?​

Answer 1

Second ionisation energy of magnesium would be low.

Explanation:

Sodium has 1 valence electron in the outermost orbit . So, after losing that electron, sodium will be in stable octal state. So, removing an electron again would require high energy. But for magnesium , the second ionisation energy would be low since it has 2 electrons in the outermost orbit .
