A. `13` electrons have spin in one direction and (11) elecrtrons in other direction
B. `14` electrons have spin in one direction and (10) elecrtrons in other direction
C. `15` electrons have spin in one direction and (9) elecrtrons in other direction
D. `15` electrons have clockwis direction and (9) elecrtrons in other direction

Answer

C

Explanation

`._(24)Cr` is : `1s^2 , 2s^2 2p^6 , 3s^2 3p^6 3d^5 , 4s^1 , 15 ` electrons in one direction ( may be clokwise or anticlockwise ) and 9 elecron in other direction.
