NEET Chemistry Ionization Energy MCQ Question
Which of the following statements about ionization energy is correct?
The first ionization energy is always greater than the second ionization energy.
Ionization energies are always positive values due to energy requirement.
Ionization energy decreases as you move down a group due to increased effective nuclear charge.
The second ionization energy is always lower than the first ionization energy because of electron shielding.
Correct Answer
Detailed Explanation
Ionization energies are always positive values because energy is required to remove electrons from an atom. The second ionization energy is typically greater than the first due to the increased difficulty of removing an electron from a positively charged ion compared to a neutral atom.
