Question

what is ionization energy?

Answer 1

$.$

A Ionization energy is the energy required to pull an electron of it's atom from its outermost shell .

Factors effecting ionization energy :

• Number of shells inversely proportional to ionization enthalpy

• Size of atom is also inversely proportional to ionization energy

• Shielding is inversely proportional to ionization energy

• Effective charge is directly proportional to ionization energy

Answer 2

The energy required to remove an electron from the outermost orbit or shell of neutral gaseous atom is called ionization energy.
