Question

Explain azimuthal and spin quantum number?

Answer 1

Azimuthal quantum number. The azimuthal quantum number is aquantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital. It is also known as the orbital angular momentum quantum number, orbital quantum number or second quantum number, and is symbolized as ℓ.

Answer 2

Hi

Here is ur answer

Azimuthal Quantum Number:

• Said by Sommerfield.
• It is represented by $l$ .
• $l$ value depends on n. l value represents subshells.
• If $l$=0 -----  s - subshell
•  $l$ = 1 ----- p - subshell
•  $l$ = 2 ----- d - subshell
•  $l$ = 3 ---- f - subshell
• If n = 1, $l$ = 0 ----- 1s
• n = 2, l = 0,1 ----- 2s 2p
• l value helps to determine orbital angular momentum.$\sqrt{l} (l+1) * h / 2\pi$
• $l$ value describes shape of the subshells.

Spin Quantum Number:

• It was said by Uhlenbeck and Goudsmith.
• It is represented by s.
• s has two independent values 1/2 and -1/2
• The value of s represents sprin of an electron.Electron may spin in two ways:
• # Clockwise(1/2)   # Anticlockwise(-1/2)
• An orbital can accomodate maximum of two electron and both should have opposite spins.
