Alkaline earth metal — Wikipedia Republished // WIKI 2

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.

Calcium is orange, sodium yellow, and copper or chlorine give a blue color. Potassium generates a light pinkish violet and rubidium a violet-red color. In 1861, Kirchhoff and Bunsen, in an experiment to extract lithium from the mineral lepidolite dissolved the ore in acid and then precipitated the potassium it contained which carried down another heavier alkali metal.

How To Make Green Fire | Science Trends

Calcium will cause flames to burn an orange color, but the color is typically rather muted so it can be difficult to differentiate it from the yellow colors of sodium. Calcium is an alkali metal that occurs naturally in various types of rocks, and calcium compounds are frequently used in food additives, pharmaceuticals, and other products.
