Question

no two electrons in the same atoms can have identical set of four Quantum numbers this statement is known as-
a) pauli's exclusion principle
b) hund's rule
c) aufbau rule
d) Heisenberg uncertainty principle​

Answer 1

Explanation:

pauli's exclusion principal

Answer 2

Answer: The correct answer is Option a.

Explanation:

For the given options:

• Option a:

Pauli exclusion principle states that no two electrons with in an atom can have all four quantum numbers same.

• Option b:

Hund's rule states that every orbital in a sublevel will be singly occupied first before any orbital is doubly occupied. Electrons when singly occupies will have the same spin.

• Option c:

Aufbau principle states that the electron will occupy the lowest energy level first before occupying the higher energy levels.

• Option d:

Heisenberg uncertainty principle states that it is impossible to measure with high precision the value of momentum and position of an electron.

Hence, the correct answer is Option a.
