Atomic Structure Question 185
Question: Identify the incorrect statements
Options:
A) An electronic wave function must be symmetrical with respect to the interchange of any two electrons
B) $ {{\psi }^{2}} $ must remain unchanged when the spin and space coordinates of the paired electrons are interchanged
C) For an n electron system the wave function $ \psi $ will be a function of 3 n spatial coordinate
D) Antisymmetrical wave function are found to represent the properties of electron.
Show Answer
Answer:
Correct Answer: A
Solution:
- Pauli-s exclusion principle states that $ {{\Psi }^{2}} $ must remain unchanged by interchange of spin and space coordinate and that is possible only if $ \Psi $ changes its sign (antisymmetrical).
