Magnesium reacts with nitrogen in the solid state if it is powdered and heated to just below the melting point, forming Magnesium nitride Mg 3 N 2. [22] Magnesium reacts with water at room temperature, though it reacts much more slowly than calcium, a similar group 2 metal. [20]
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

This review notes several key points in the history of research regarding magnesium. For a while, the understanding was that magnesium deficiency was not a major issue and that if it was, it was ...
Melting points (in blue) and boiling points (in pink) of the first eight carboxylic acids (°C). For most substances, melting and freezing points are approximately equal. For example, the melting and freezing points of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). [2]
A generous sprinkle of rock salt on sidewalks, driveways, roads, and bridges melts ice away by lowering the freezing point of water. A thin layer of water forms, causing the ice to break up ...
