Beryllium is an alkaline earth metal, atomic nuer 4. Its melting point is 1278 celsius (2332F/1551K). In comparison, magnesium has a melting point of 649C (1200F/922K), calcium is 839C (1542F/1112K), strontium is 769C (1416F/1042K) and barium is 725C (1337F/998K).

22.4: The Alkaline Earth Metals (Group 2) - Chemistry

26/11/2013· Because of their higher positive charge (+2) and smaller ionic radii, the alkaline earth metals have a much greater tendency to form complexes with Lewis bases than do the alkali metals. This tendency is most important for the lightest ion (Be 2 + ) and decreases rapidly with the increasing radius of the metal ion.
