MCQ
Which of the following sets of quantum numbers represents the highest energy of an atom?
  • A
    $n=3,l=0,m=0,s=+1/2$
  • B
    $n=3,l=1,m=1,s=+1/2$
  • $n=3, l =2, m= 1, s=+1/2$
  • D
    $n=4,l=0,m=0,s=+1/2.$

Answer

Correct option: C.
$n=3, l =2, m= 1, s=+1/2$
c
In which quantum number have highest $(n+l)$ value, will represent highest energy of an atom.

$ \mathrm{n}+l=3+2=5=$ maximum.
