"No two electrons in an atom can have the same set of all four quantum numbers". This principle is called (A) Zeeman Effect (B) Pauli's Exclusion Principle (C) Stark Effect (D) Heisenberg Principle

Pauli's exclusion principle is, "No two electrons in an atom can have the same set of all four quantum numbers". e.g. for 4 s2 configuration, its n l m s 1st e- =4 0 0 +1/2 2nd e- =4 0 0 -1/2

	$n$	$l$	$m$	$s$
$1 s t e^{-}$	$= 4$	$0$	$0$	$+ 1/2$
$2 n d e^{-}$	$= 4$	$0$	$0$	$- 1/2$

Zeeman Effect

Pauli's Exclusion Principle

Stark Effect

Heisenberg Principle

Pauli's exclusion principle is, "No two electrons in an atom can have the same set of all four quantum numbers".
e.g. for $4 s^{2}$ configuration, its

$n$ $l$ $m$ $s$

$1 s t e^{-}$ $= 4$ $0$ $0$ $+ 1/2$

$2 n d e^{-}$ $= 4$ $0$ $0$ $- 1/2$
