Question

Which of the following has maximum ionisation potential?
(a) Al. (b) P. (c) Si. (d) Mg

Answer 1

Heya mate
The answer of ur question is

Answer
Maximum ionisation potential energy is of Mg i.e ( Magnesium ) because the ionisation energy increase from right to left in a group. ..



hope it helps

Answer 2

Answer:

(d) Mg

Magnesium has maximum ionization potential.

Explanation:

Magnesium has the highest ionization potential energy because its ionization energy rises from right to left within a group. However, due to the filled-shell electron structure of the Mg2+ ion, magnesium has a very high third ionization energy. Therefore, since Mg2+ has the highest ionization energy, it is the proper response. Because magnesium has one additional proton in its nucleus to hold on to the electrons in the 3s orbital, its first ionization energy is higher than sodium's. Calcium has a higher initial ionization energy than magnesium due of the smaller radius of calcium. Magnesium's smaller radius enables it to have a higher ionization energy. Magnesium has a higher initial ionization energy than aluminum.
