MCQ
Which of the following elements outermost orbit's last electron has magnetic quantum number $m=0$ ?
- ✓$Na$
- B$O$
- C$Cl$
- D$N$
✓
Answer
Correct option: A.
$Na$
a
$m$ equals to zero corresponds to the $s$ electron, which is the last electron of the element should be an $s$ electron.
$m$ equals to zero corresponds to the $s$ electron, which is the last electron of the element should be an $s$ electron.
For $Na ,\, 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1}$
