NEET Chemistry Ionization Energy Assertion Reason Question
Assertion (A): Ionization energy generally increases across a period from left to right.
Reason (R): The effective nuclear charge increases across a period, pulling the valence electrons closer to the nucleus.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
Both the assertion and the reason are true, and the reason correctly explains the increase in ionization energy across a period due to increased effective nuclear charge.
