The second ionisation energy of sodium(na) is very high as compared to its first ionisation energy

The reason the second ionization energy is higher than the first relates to the attraction between the electrons and the nucleus.

When one attempts to remove a second electron from a positive ion, there is more attraction between the electrons and the nucleus due to the extra proton.

Because it acquires stable noble gas configuration after losing one electron.

Explanation:

The ionization energy is the energy required to remove an electron from the valence shell of an isolated gaseous atom of an element.

Now the ionization energy depends upon

a) size of an element ,larger the size more lesser the effective nuclear charge on electron thus lower the ionization energy.

b) the electronic configuration of an element. If on losing an electron an element attains noble gas configuration or half filled stability then it will easily lose an electron.

In case of sodium with atomic number of 11, it has electronic configuration of 2,8, 1. On losing one electron it acquires stable noble gas configuration of 2,8 and thus it gets difficult for the loss of second electron and The second ionisation energy of sodium is very high.
