WebScandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it wasn't until the 1960s when the first pound, or 450 grams, of high purity scandium was obtained. Compounds of scandium find use in organic chemistry. WebApr 5, 2024 · For example, scandium has too many d electrons and hence very few orbitals to share electrons with others for very high valence. The variable oxidation states in valence electrons are due to the very few amount of electrons that are filled in d-orbital in such a way that their oxidation states differ from each other by a unitary.
