Question

What are the factors influencing ionization enthalpy? The exam is for 60 marks and the question is for 2 marks. I have written,only Atomic size and nuclear charge and given explanation for it. Can i get complete marks for it?

Answer 1

1. size of positive nuclear charge.as a nuclear charge increases the attraction for the outermost electron increases, and more energy is required to remove an electron
2. size of atom (distance of outermost electron from the nucleus).
3. screening effect of inner shell electrons

Answer 2

$\boxed{ \boxed{ \boxed {\huge\bold\pink {Answer}}}}$

3 Factors Affecting Ionisation Energy

• Size of the positive nuclear charge. As the nuclear charge increases, its attraction for the outermost electron increases and more energy is required to remove an electron.
• Size of atom (distance of outermost electron from the nucleus)
• Screening (shielding) effect of inner shell electrons.
