Q. |
"All the four quantum numbers of two electrons in an atom are not the same." It is the law of |
A. | Hund’s |
B. | Exclusion Principle of Pauli |
C. | Uncertainty Principle of Giesenberg |
D. | Avogadro’s law |
Answer» B. Exclusion Principle of Pauli | |
Explanation: The Pauli exclusion principle is the quantum mechanical principle that no two identical fermions (particles with half-integer spin) may occupy the same quantum state simultaneously. A more rigorous statement is that the total wave function for two identical fermions is anti-symmetric with respect to exchange of the particles. |
