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)

Both magnesium and calcium are in the second vertical column on the periodic chart. Like all Group 2 elements, magnesium and calcium are alkaline earth metals. They are both soft, silver-colored metals that react quickly with halogen gases such as fluorine
In addition, the element is also useful for sedating patients. Magnesium carbonate, a popular compound of the alkaline earth metal, is essential to strengthen or to enhance athletes’ grips on things. Finally, the metal is used for the production of paper as well as
The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be 2+, Mg 2+, Ca 2+, and so on). These metals are less reactive than the neighboring alkali metal. Magnesium is less active than sodium; calcium is less active than potassium; and so on.
