help with simple stuff electron config 1s2 etcin GENERAL when your doing the electron config for lets say a positive ion the electrons are lost from the sub shell with the HIGHEST energy
I know that there is an exception to this with chromium and copper that prefer to loose an electron from the 4s before loosing them from anywhere else
However I was looking at some stuff at the Internet and found that this is not just true for copper and chromium but for all the transition metals <<< is that true? (or may I have understood something wrong)
only need to know how to do this stuff for Z=36 so if there are other complications beyond here don't tell me lolLast edited by CasualSoul; 07-05-2012 at 14:43. -

Re: help with simple stuff electron config 1s2 etcTransition metals fill the 4s before the 3d, but they actually lose the 4s before the 3d when they form an ion. So yes it is true.(Original post by CasualSoul)

However, Chromium and Copper are exceptions as only one electron takes the 4s orbital so Cr = [Ar] 3d54s1 and Cu = [Ar] 3d104s1 as to achieve a more stable arrangement of lower energy.
E.g. in Cr; 6 unpaired electrons with lower repulsion.
