Question

what is meant by ionisation energy?

Answer 1

The ionization energy (IE) is qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.

Answer 2

✌️✌️ hey mate,

➡️Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

➡️The first or initial ionization energy or Ei of an atom or molecule is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions.


thanks...
nice to help you ✌️✌️
