Question

Teosons -
2 . The second ionination energy of
sodium is
on is very high as compared to its
first ionination energy​

Answer 1

Answer:

The second reason is that you have just created a positive ion which means that the positive charge will more strongly pull the outer electrons to the nucleus making it harder to ionise sodium a second time. Ionisation energy has a trend and as you ionise every element follows the same trend because of these reasons.
