How many electrons in an atom may have the following quantum numbers:(a) n = 4, ms = -1/2(b) n = 3, l = 0 |
|
Answer» (a) For n = 4, No. of subshells = 4s, 3d, 4p. Total no. of electrons which can be present = 2 + 10 + 6 = 18 Total no. of electrons with ms value of -1/2 = 9 (b) l = 0 describes a s-orbital. A 's' orbital can accommodate only two electrons at the most. Therefore, 2 electrons can have the quantum numbers, n = 3 and l = 0 |
