Highest melting point elements
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 … WebInteractive periodic table with element scarcity (SRI), discovery dates, melting and boiling points, group, block and period information.
