What Are the Properties of Calcium? (with pictures)
17/7/2020· Calcium is considered to be a metal. The general properties of calcium include limestone, chalk, gypsum, marble, and plaster. In terms of chemistry, calcium belongs to an element family called alkaline earth metals. Similar metals include magnesium and radium. Milk is a good source of calcium
Calcium - Periodic table
Calcium was first isolated by Sir Humphry Davy in 1808 in London. In a lecture to the Royal Society in June 1808, Davy described his experiments that year, which produced tiny amounts of metal, at best. He could not find any way to produce more calcium (3)
Who Discovered Calcium? - Who Discovered It
Calcium is classified as an alkaline earth metal that is a bit hard and is silvery white in color. Its melting point is around 839 +/-2 degrees C and boiling point is around 1484 degrees C. Its specifiion for gravity is at 1.55 or is equivalent to twenty degrees C, and its valence is two.

What are the uses of alkaline earth metal? | eNotes
Alkaline earth metals refer to a group of elements in the periodic table. They include beryllium, magnesium, calcium, strontium, barium, and radium. Main uses of these elements are given below.
Understanding Alkalinity and Acidity – Named Program
Among the alkaline earth metal hydroxides, calcium and magnesium are the strongest in terms of alkalinity in an aqueous solution. Calcium hydroxide is not quite as strong a base as potassium hydroxide or sodium hydroxide because it is only relatively soluble where the other two completely dissociate.
Lanthanum - Wikipedia
Lanthanum is a chemical element with the syol La and atomic nuer 57. It is a soft, ductile, silvery-white metal that tarnishes slowly when exposed to air and is soft enough to be cut with a knife. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype.
