Question : 31
Total: 67
How many electrons in an atom may have the following quantum number?
(a) n = 4,m s
(b) n = 3, l = 0
(a) n = 4,
(b) n = 3, l = 0
Solution:
(a) Total number of electrons in n = 4 is 2 n 2 2 ( 4 ) 2
But half of these electrons havem s
∴ Number of electrons = 16
(b) Number of electrons = 2 [Since 3s subshell]
But half of these electrons have
∴ Number of electrons = 16
(b) Number of electrons = 2 [Since 3s subshell]
