Question

write the electronic configuration of cu2+ ion (z = 29 )

Answer 1

Hi friend,

Step 1 :-

Write down the electron configuration of the atom.


Step :- 2

The ion has a 2+ charge so two electrons are removed . one is taken from the 4s sub-shell , the other from 3rd sub-shell.

So, the electron configuration of Cu2+ is :-

1 s2 2 S2 2 p6 3S2 3p6 3d9

.....i hope it helps you
