Question

which of the following configuration would you expect to have the highest second ionization energy​

Answer 1

The alkali metal would have the highest value of the second ionization energy.

Explanation:

• The alkali metal has one electron more than the inert gas configuration.
• Hence when the iron loses the second electron a large amount of energy is required to remove the second electron from the noble gas electronic configuration.
• Hence a large amount of energy is required. This energy is known as a second ionization energy.
• The second ionization energy is highest for the alkali metals and lowest for the group 2 two metals such as calcium and magnesium.

Why the second ionization energy is greater than the first one?
