Transition Metal Characteristics Partially occupied d sublevels lead to the possibility of o Multiple oxidation states o Colored compounds o Magnetic properties Oxidation States o For the period four transition elements When cations are formed They lose the 4s electrons first From Sc to Mn the maximum oxidation state is the sum of 4s and 3d electrons After Mn, the maximum oxidation number decreases until Zn, which is only +2 Magnetism o Electrons possess spin, causing a magnetic moment o When all electrons are spin-paired, the moments cancel each other out.
