Electron configurations of d block elements

Postby Ella Bouris » Tue Dec 05, 2017 10:17 pm

Do the electron configurations for the d block transition metals all have a 4s1 subshell? Or just the two exceptions Cu and Cr?

Hello,

Only the exceptions will have the electron configuration with 4s1. The exceptions are the elements in group 6 and group 11, which does include Cu and Cr.

Yes, it is just these exceptions, as it is more stable to have the d-orbital filled and only half of the s-orbital filled.
