MCQ
The possible values of principal quantum number can be:
- ✓$1, 2, 3...8$
- B$0, 1, 2...8$
- Conly zero
- Donly odd numbers
✓
Answer
Correct option: A.
$1, 2, 3...8$
Values of Principle quantum number are $1, 2, 3, 4.....8. 0$ is not a Principle quantum number.
Only odd numbers are not Principle quantum numbers either.
Odd numbers, as well as even numbers, are Principle quantum number except $0$ and negative integers.
