Q. Explain Pauli Exclusion Principle?
When assigning electron configurations, it is essential to consider the two important principles concerning electrons in orbitals:
No more than 2 electrons can fit into a single orbital If 2 electrons are in the same orbital, they must have opposite spins (ms = +1/2 for one and -1/2 for the other)
A law known as the Pauli Exclusion Principle explains how these same criteria are obeyed in assigning quantum numbers to a given electron. The Pauli Exclusion Principle States: No two electrons can have the exact same set of four quantum numbers n, l, ml, and ms.
The maximum number of electrons that can be accommodated in a 3d subshell is: (1) 2 (2) 10 (3) 6 (4) 14 Ans: 10
