NEET Chemistry Ionization Energy MCQ Question
Type: MCQ-fact-Hard-Class 11
What effect does shielding have on the ionization energy of an atom?
A
It decreases the effective nuclear charge felt by the valence electrons.
B
It increases the ionization energy of the atom.
C
It has no effect on ionization energy.
D
It makes the valence electrons more attracted to the nucleus.
Correct Answer
Option A
Detailed Explanation
Shielding reduces the effective nuclear charge experienced by the valence electrons, making it easier to remove them, which in turn decreases the ionization energy.
