MCQ

The incorrect statement among the following is

A
The first ionization potential of $Al$ is less than the first ionization potential of $Mg$
✓
The second ionization potential of $Mg$ is greater than the second ionization potential of $Na$
C
The first ionization potential of $Na$ is less than the first ionization potential of $Mg$
D
The third ionization potential of $Mg$ is greater than the third ionization potential of $Al$

✓

Answer

Correct option: B.

The second ionization potential of $Mg$ is greater than the second ionization potential of $Na$

b
After removal of an electron sodium acquires stable noble gas configuration. It is difficult to remove electron from stable noble gas configuration species. Therefore, second ionization potential of $Mg$ is less than that of $Na$.
