Electron configuration for Ag

[Riya Sood 4G]

Is this the correct electron configuration for Ag (Silver):

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s1

Does the 5s1 go last or the 4d10?

the 5s1 goes last

[Aarja Pavade 1H]

When we looked at the Scandium example, we saw that the right way to write the electron configuration was [Ar]3d14s2 because for multi-electron atoms after atomic number 20 the 4s state is higher in energy than 3d. Period 5 shows this same trend where after 2 electrons have occupied the 5s state the 4d state is lower in energy than the 5s state. Thus, for Ag the 5s1 would come after 4d10.
