Explain pauli's exclusion principle with suitable example

Answer 1

$\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}$

According to the pauli's exclusion principle : No two electrons in an atom can have the same set of four quantum numbers.

⠀ ⠀Or we can say that :

⠀⠀ ⠀ ⠀⠀" Only two electrons may exist in the same orbital and these electrons must have opposite spin."

$\red\bigstar \color{green} \bf FOR \: EXAMPLE :$

• n=1, n=1
• l=0, l=0
• $\sf m_l = 0 , m_l = 0$

for the 1s subshell. Only two electrons can have these numbers, so that their spin moments must be either

• ms= −½ or ms = ½

Answer 2

Answer:

Example of the Pauli Exclusion Principle The exclusion principle asserts that every electron in an argon atom is in a unique state. The 1s level can accommodate two electrons with identical n, l, and ml quantum numbers. ... The pair of 2s electrons differ from each other because they have opposite spins.
