I noted in inorgchem class that....
"Fe[N(SiMePh_2)_2]_2"
"when two ligands coordinate with Fe ( which is neutral),
electron configuration changes [Ar]4s^2 3d^6 to [Ar]3d^8 "
I forgot why... does two electrons of 4s move to 3d orbital??? why???.
57. Which electron is, on average, closer to the nucleus: an electron in a 2s orbital or an electron in a 3s orbital?
