A great deal of recent data related to calcium intake and its effects on calcium balance, bone mass, and the prevention of osteoporosis was reviewed, with attention given to the calcium requirements over the life cycle. The current Recommended Dietary Allowances(RDA) (10th edition, 1989) for calcium intake were considered as reference levels and used as guidelines to determine optimal calcium
Is Beryllium Chloride, BeCl2, ionic or covalent? : chemhelp
8/11/2010· What your teacher wants you to recognize is that BeCl2 is created from an alkaline earth metal and a halogen. Generally, metal+halogen gives an ionic compound. For a test or something, I''d say learn the trend - metal + halogen = ionic, rather than worry about Pauling values for bonds that happen to be very close to 50% ionic.
