Scandium

Scandium"Scandium": Peter van der Krogt, "Elementa chemica" apud situm Elementymology & Elements Multidict (ex Scandinavia nominatum ubi primum repertum est) elementum chemicum est, metallum transitionis cisuranicum glaebae d, cui numerus atomicus 21 (id est, cum 21 protonibus in nucleo suo), et symbolum Sc, massa vero atomica 44,955 quia scandium-45 (21 protones et 24 neutrones) in natura longe praevalet. In systemate periodico in quartam periodum et gregem tertium ponitur.  Statu normali solidum et multum molle est et apparentiam candidam argenteam habet; inventum 1879 per analysin spectralem euxenitae gadolinitaeque Scandinaviae est sed tantum anno 1937 per electrolysim purificatum; historice classificatum ut metallum terrenum rarum est cum yttrio et lanthanidis.

 De proprietatibus chemicis 
Scandium facile cum aqua reagit. Gradus oxidationis solitus est +3 (configuratio electronica 3d14s2). Temperatura qua liquidum fit: 1540 gradus Celsiani. Qua gas fit: 2800 gradus Celsiani. Massa per volumen: 2,99g/cm3.

Proprietates compositorum scandii inter proprietates compositorum aluminii yttriique mediae sunt.
