Melting point

• Why Do Alkaline Earth Metals Usually Melt at Higher Temperatures?
  Alkaline earth metals usually melt hotter than neighboring alkali metals, but band filling alone cannot explain the trend or predict melting points.
• How to Calculate Melting and Boiling Points at Different Pressures
  Use the Clausius–Clapeyron equation for boiling points and the Clapeyron equation for melting points, with a reference temperature and phase-change data.
