Lanthanide Contradiction
Electrons in an f subshell are not very effective in screening outer-shell electrons from the nucleus. As a result, the outer shell electrons are held more tightly by the nucleus than we would otherwise expect. Atomic radii do not increase. In fact in the series of elements in which the 4f subshell is filled, atomic radii decrease somewhat.
Similarities between First Transition Series
- an inner core of electrons in the argon configuration
- two electrons in the 4s orbital for 8 member and one 4s electron for the remaining two (Cr and Cu)
- a number of 3d electrons, ranging from one in Sc to ten in Cu and Zn
Geometry
6 ligands more splitting than 4 ligands
Oxidation state of metal
Greater oxidation state--> greater splitting
Size of metal
Larger M-->greater splitting
Strength of Field
Stronger field --> greater splitting
