NEET Chemistry Quantum Mechanical Model Assertion Reason Question
Assertion (A): The energy of an electron in an s orbital is more negative than that in a p orbital of the same shell.
Reason (R): The s orbital electron is more tightly bound to the nucleus than a p orbital electron due to its 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.
Correct Answer
Detailed Explanation
The energy of electrons in s orbitals is lower (more negative) than in p orbitals because the s orbital electron is more tightly bound to the nucleus, as it spends more time close to the nucleus due to its spherical shape.
