Scandium subgroup
WebGroup III consists of two subgroups: group IIIb and group IIIa. Group IIIa consists of scandium, yttrium, and lanthanium, which is generally considered with the lanthanoids, and actinium, which is classified with the actinoids. Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium. Show source. WebScandium Subgroup. Group 3B is aka. Sc, Y, La, Ce, Ac, Lanthanides, Actinides. Group 3B elements. Scandium. Eka-boron. Cerium Sulfate. Only cerium compound used in analytical chemistry as primary titrant in the redox titration - cerimetry. Thallium. Most toxic and absorbed in the intestine and through the skin from ointments and creams.
