Lanthanum standard state of matter
WebbHow many states of matter there are depends on whom you ask and how they distinguish phases. This count could range anywhere from 5 or 6, to hundreds. But for a beginning chemistry student, there are only four that are important. Plasma is mainly important in understanding lightning and certain modern technologies. WebbLanthanum is a chemical element of group III, of the yttrium subgroup. Natural lanthanum is composed of two isotopes: stable La-139 (99.911%) and radioactive La-138 (0.089%) with a half-life period of 2·1011 years. The electron shell configuration of lanthanum is 5d1 6s 2, and its main oxidation state is 3+.
