Question

explain 3rd ionization energy of Mg is 10 times higher than that of 1st ionization energy. ​

Answer 1

Explanation:

during Ist ionisation energy :12 electrons become 11electrons

during IInd ionisation energy :11 electrons become 10 electrons which is equal to the number of electrons of inert gas neon thus mg2+ became inert , but due to this-

During IIIrd ionization energy : 10 electron need higher energy to remove as it had achieved inert gas configuration

Thus III ionization energy is 10 times faster than Ist ionization energy
