In Cu (At. no. = 29)...

In Cu (At. no. = 29)

A

13 electrons have spin in one direction and 16 electrons in other direction

B

14 electrons have spin in one direction and 15 electrons in other direction

C

one electron can have spin only in the clockwise direction

D

none of the above is correct.

Text Solution

Verified by Experts

The correct Answer is:
B
`._(29)Cu = [Ar[^(18) 3d^(10) 4s^(1)`
All electrons are paired except `4s^(1)`. Hence, `14e^(-)` have spin one direction and `15 e^(-)` in the other
