Question

discuss the various factors affecting ionization ethalpy.​

Answer 1

Answer:

Answer 2

Answer:

Ionization enthalpy is a minimum amount of energy required to remove an electron from the outermost orbital. Ionization enthalpy of the main group elements tends to decrease down the group due to the following factors such as atomic size, shielding or screening effect and nuclear charge
