write electronic configuration of CU + atomic number of CU is equal to 29

Which class are you studying?
11th
If you are in class 11 than my answer would not satisfy you because then I would need to go to S shells which I don't know

At first it would look like
K = 2 L = 8 M = 18 N =1
But that's not the case
We will fill it one by one
At max K can have 2 electrons
K= 2
L at max can hold 8 electrons
L = 8
M at max can hold 18 electrons but the outermost shell cannot have more than 8
So, M = 8
N at max can hold 32 electrons but outermost can only hold 8
So, N = 8
Now we need 3 more electrons but earlier we saw M can hold 18 but we gave only 8 to it
So, we will give three electrons to M and it will become
M = 11
Thus, your answer must be
K =2 L = 8 M = 11 N = 8
Hope it help.
