Where Was Calcium Discovered And The Nature Of It's Discovery?

In 1808 Sir Humphrey Davy discovered Calcium in England. Although the compounds of calcium like lime were prepared in the age of Romans in the first century and it was known as Calx, however, its identification as an element is credited to Sir Davy. In this discovery, calcium was isolated through the process of electrolysis of a mixture of lime and mercuric oxide (HgO).
