NEET Chemistry Orbitals Assertion Reason Question
Assertion (A): Electrons in s orbitals shield the outer electrons from the nucleus more effectively than those in p orbitals.
Reason (R): Electrons in s orbitals spend more time close to the nucleus due to their spherical shape.
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 but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that s orbital electrons shield outer electrons more effectively and spend more time near the nucleus due to their spherical shape, thus explaining the assertion.
