Answer:
atomic number 29 is Copper
Explanation:
The electronic configuration of copper is 2,8, 18, 1.
It can also be written as 1s2 2s2 2p6 3s2 3p6 3d10 4s1 4p0 or [Ar]3d10 4s1 4p0 .
n shell = 11 electrons
l shell = 8 electrons
Verified answer
Actually the electronic configuration of the above answer is correct but the value of n and l is wrong.So value of n,ie, principal quantum no will be 4
And value of l ie azimuthal quantum no will be 0,1,2,3
