JEE MAIN - Chemistry (2021 - 16th March Evening Shift - No. 18)
The number of orbitals with n = 5, m1 = +2 is ___________. (Round off to the Nearest Integer).
Answer
3
Explanation
Given, n = 5, ml = + 2
For n = 5, possible value of l = 0, 1, 2, 3, 4
For l = 0, ml = 0
l = 1, ml = $$-$$1, 0, 1
l = 2, ml = $$-$$2, $$-$$1, 0, 1, 2
l = 3, ml = $$-$$3, $$-$$2, $$-$$1, 0, 1, 2, 3
l = 4, ml = $$-$$4, $$-$$3, $$-$$2, $$-$$1, 0, 1, 2, 3, 4
Possible value of ml for a given value of l
= 0, $$\pm$$ 1, $$\pm$$ 2, $$\pm$$ 3 ..... $$\pm$$ l
So, number of orbitals having n = 5 and ml = $$\pm$$ 2 are 3.
