Abstract

The trace elements of Group 2, beryllium (Be), strontium (Sr), and barium (Ba), belong to the alkaline earths and behave similarly to Ca and Mg. Their physical properties, especially sizes of their ionic radii are fairly similar to those of Ca, and they may substitute for each other, however, the small ionic radius of Be prevents its replacement by other cations (Table II-2.1). All the alkaline earths are associated with the carbon cycle that strongly controls their behavior in the terrestrial environment. Radium (Ra), which occurs as several radionuclides, also belongs to this group, and is a product after the decay chain of U and Th.
