MCQ
An electron has a spin quantum number $+1/2$ and magnetic quantum number $-1.$ It cannot be present in :
- A$d-$ orbital
- B$f-$ orbital
- ✓$s-$ orbital
- D$p-$ orbital
For $l=0$, malue should be $0$ indicates $s$ orbital.
For $l=1$, malue should be $-1,0,+1$ indicates $s, p$ orbitals.
For $l=2$, malue should be $-2,-1,0,+1,+2$ indicates $s , p , d$ orbitals.
Fore $l=3$, malue should be $-3,-2,-1,0,+1,+2,+3$ indicates $s , p , d$ orbitals.
For $l$ value $-1$ the electron may present in $p$ or $d$ or $f$ orbital
