12 Metallic Behavior/Reducing Strength Lower oxidation state = more metallic
13 Magnetic properties due to unpaired electrons Color and Magnetisme- in partially filled d sublevel absorbs visible lightmoves to slightly higher energy d orbitalMagnetic properties due to unpaired electrons
25 LigandsMolecule or ion having a lone electron pair that can be used to form a bond to a metal ion(Lewis base).coordinate covalent bond: metal-ligand bondmonodentate: one bond to metal ionbidentate: two bond to metal ionpolydentate: more than two bonds to a metalion possible
