WebScandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An … Web10 de jul. de 2015 · 27. The melting and boiling points of transition elements increase from scandium ( 1530 ∘ C) to vanadium ( 1917 ∘ C ). They increase because as we go across the group, we have more unpaired (free) electrons. But at chromium ( 1890 ∘ C) however, the melting point decreases even though it has more unpaired electrons than the …
