IONISATION ENERGY

If ionising energy of H atom is 13.6 eV, then the second ionising energy of He should be

a. Explain why the second ionisation energy of B is significantly higher than the second ionisation energy of C , even though the first ionisation energy of B is less than C . b. which has higher 1st ionisation energy B or Be and why?

Alkali metals have low ionisation energies. Explain.

In view of their low ionisation energies, the alkali metals are

The ionisation energies of tranition elements are:

The factors that influence the ionisation energies are

The factors that influence the ionisation energies are:
