Question

c) How many of electrons in an atom
may have the following auantum nos i n=4 ms = 1/2​

Answer 1

Explanation:

The Maximum no of electrons in 4th energy level =2×n

2

=2×4

2

=32 electrons

In 32 electrons half the electrons have m

s

=−

2

1

and the other have m

s

=+

1

So total no of electrons having n = 4 and m

s

=−
