Officer Sir Humphry Davy

Humphry Davy was a British chemist known for his experiments in electro chemistry. He was born on December 17 1778 in Penzance, Cornwall. He died the 29th of May 1829. He was knighted, made a baronet, and became the president of the Royal Society.

Report of Calcium's first arrest:

Metallic calcium was isolated for the first time by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).

Last Seen:

  • Chilling with Potassium on the periodic table
  • never found free in nature since it easily makes compounds by reacting with air and water

Known Associates:

Calciums makes mixtures/compounds with









citric acid

it rapidly forms a gray-white coating of calcium oxide and calcium nitride for reacting with the oxygenated nitrogen in the air when exposed to it.

Warning Label

Calcium phosphide is very toxic to aquatic organisms.
