Element X : M shell= 18 electrons
M shell means n= principal quantum number =4 and N shell = 1 electron.
N shell means n = principal quantum number =4
Therefore, element X=Cu with electronic configuration as :
Cu : 1s 2 2s 2 2p 63s 2 3p 63d 10 4s 1
Other elements of group 11 are Cu (Copper), SIlver (Ag) and Gold (Au).
