NEET Chemistry Quantum Mechanical Model Assertion Reason Question
Assertion (A): The Heisenberg uncertainty principle implies a fundamental limit to the precision with which certain pairs of physical properties, such as position and momentum, can be known simultaneously. | Reason (R): The quantum mechanical model of the atom allows for precise determination of both position and momentum of an electron.
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 Heisenberg uncertainty principle states that there is a limit to the precision of simultaneous measurements of position and momentum. The quantum mechanical model does not allow for precise determination of both position and momentum.
