How many sub-shells are associated with n = 4?
Advertisements
उत्तर १
n = 4 (Given)
For a given value of ‘n’, ‘l’ can have values from zero to (n – 1).
∴ l = 0, 1, 2, 3
Thus, four sub-shells are associated with n = 4, which are s, p, d and f.
उत्तर २
n = 4, l = 0, 1, 2, 3. 4 sub-shells are associated with n = 4
