Question

how many unpaired electrons of cu​

Answer 1

Answer:

5 is the impaired electrons of Cooper.

Answer 2

Answer:

In an s sub-shell, there is 1 orbital so an s sub-shell can hold a maximum of 2 electrons. A p sub-shell has 3 orbitals to hold a total of 6 electrons. A d sub-shell has 5 orbitals that can hold a total of 10 electrons. From this, we can see that copper has 1 unpaired electron.
