Question

What are the factors influencing ionization enthalpy? The exam is for 60 marks and the question is for 2 marks. I have written,only Atomic size and nuclear charge and given explanation for it. Can i get complete marks for it?

Answer 1

Explanation:

The Ionization Energy depends on two factors, which are:

The force of attraction between electrons and the nucleus.

The force of repulsion between electrons.

The effective nuclear charge felt by the outermost electrons will be less than the actual nuclear charge. This is because the inner electrons will shield the outermost electrons by hindering the path of nuclear charge. This effect is known as the shielding effect. For example, In Na, the 3s1 electrons will be shielded by its core electrons (1s2, 2s2 and 2p6). Generally, shielding effect is more prominent when the inner orbitals are completely filled.
