Question

please solve all the above questions​

Answer 1

Answer:

155. c) 5

Total 10 electrons can be there in a d-orbital

5 with +1/2 spin and 5 with -1/2 spin

156. c) Pauli's exclusion principle

As according to this principle, no two electrons can have same value for 4 quantum numbers.

157. d) Spin quantum number

As one will have -1/2 & other will have +1/2 spin

158. b) 3,1,0,-1/2

As last electron will be in p orbital, so p = 1 and spin can never be 0, it is either-1/2 or +1/2. So, option b is correct.

hope this will help you
