Question

How many electrons in an atom may have n = 4 and ms = + 1/ 2?

Answer 1

Answer:

n = 4 and ms value -1/2

Explanation:

Solution:

n = 4 , so there are 32 electrons present in 4rth orbit (2n

2

=2×2

2

=32)

If 32 electrons then there must be a 16 orbitals and each orbital contain 2 electrons one have m

s

value -1/2 and other have m

s

value +1/2

So there are 16 electrons have quantum number n = 4 and ms value -1/2
