KnowraScandiumLinked fromLinked fromThe 9 pages that link to Scandium, each with the reason it gives.All 9Broader topic 5Related 1Compared with 3Rare-earth elementBroader topic: Scandium is included despite its different position and lighter mass because its chemistry resembles the group’s.Dmitri MendeleevBroader topic: Its properties confirmed Mendeleev's prediction of eka-boron.YttriumCompared with: Its position above yttrium in group 3 makes it a useful comparison in chemistry and materials.CeriumCompared with: Scandium shows how the broad rare-earth label extends beyond the lanthanides, unlike cerium.d-blockBroader topic: Scandium is a boundary case because its common ion has no d electrons.LutetiumCompared with: Its shared rare-earth label contrasts with its position outside the lanthanide series.Per Teodor CleveRelated: Its discovery by Cleve’s colleague illustrates the period’s rapid progress in Swedish elemental chemistry.Period 4 elementBroader topic: It is the first Period 4 element in which the 3d subshell begins to fill.Group 3 elementBroader topic: It is a conventional Group 3 member and illustrates the group’s early transition-metal chemistry.
