$\begingroup$ I''m not sure I''d consider 922 K (Mg) relative to 1112 K (Ca) exceptionally low. And given Sr (1041 K), Ba (1002 K) and Ra (973 K) perhaps the question might be why is calcium''s melting point a tad higher than you might expect. Now if magnesium''s
Calcium definition, a silver-white divalent metal, occurring coined in limestone, chalk, gypsum, etc., occurring also in vertebrates and other animals, as a component of bone, skeletal mass, shell, etc., and as a necessary element in nerve conduction, heartbeat
Calcium chloride is clearly superior to other materials for melting ice. It’s the fastest, most effective ice-melt material available, melting and penetrating ice at lower temperatures. For more than 100 years,calcium chloride products have helped make the surfaces of
