Ionsation energy can be defined as the minimum energy required to take out the outer most loosely bound electron .
For example - An atom has 3 shells and there is a loosely bound electron in the outermost shell . So the energy given to the atom in order to take that elelctron out of the orbit of an atom will be defined as the ionisation energy of that atom.
Hope that helps.

energy required to remove an electron from the outermost shell of the atom of a compound
OR
energy required to convert a compound into 2 or more ions
factors on which ionization enthalpy depend are:-
1.difference in atomic size-as the difference in atomic size increases IE decrease
2.electronegativity-as the electronegativity difference between 2 atoms increase IE decrease
3.nuclear charge-as the nuclear charge increase IE increase
4.size of the compound-as the size of the compound increase von der waals force increase hence IE increase
5.hybridisation-IE increase for sp3>sp2>sp
