Question

what is ionisation enthalpy??

in simple words ⠀⠀⠀​

Answer 1

Explanation:

Ionization enthalpy of an element can be defined as the amount of energy required to remove an electron from an isolated gaseous atom in its gaseous state.

hope it helps you......☺☺☺☺

Answer 2

In simple words:-

We can define Ionistaion Enthalpy of an element as the amount of energy required to remove an electron from an isolated gasesous atom in it's gaseous state.

_____________________________

Ionisation Enthalpy depends on the following three factors:-

•Electronic Configuration

•Penetration effect

•Shielding effect

Electronic Configuation:-

Elements which have half filled or full filled orbitals are stable, and if we try to remove an electron from these orbitals, will make them less stable. Thus, we can infer that higher amount of ionisation energy is required to remove an electron from these orbitals.

Penetration effect:-

Penetration refers to the proximity of an electron in an orbital to the nucleus. If we look into the radial probability distribution functions, we see that density of s orbitals are closer than that if p and d orbitals.

Shielding effect:-

It can be defined as the effect in which the inner electrons develop a shield for the elctrons in outer shells which does not let the appropriate nuclear charge towards the outermost electrons.
