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 … WebWe observe a common trend in properties as we move across a period from left to right or down the group. This trend in properties is known as periodic properties. The important periodic properties are atomic size, metallic character, non-metallic character, ionization potential, electron affinity, and electronegativity. Periodic Table Trends.
