Calcium - The Environmental Literacy Council

Soils in humid regions generally have less calcium than those in dry regions, and calcium is often added to the soil in humid regions to reduce acidity. Calcium levels in soil don’t seem to affect human nutrition, because the amount of calcium taken up by a plant depends much more on the nature of the plant species than it does on the calcium content of the soil.

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.

The Parts of the Periodic Table - Angelo State …

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).They are harder and less reactive than the alkali metals of Group 1A. The name comes from the fact that the oxides of these metals produced basic solutions when dissolved in water, and they remained solids at the temperatures
