  1. “Hey Cal, see ‘em?!” Savannah Phinney Honors Chemistry Adopt an Element Project

  2. Description • Classification: Alkali Earth Metal • Color: silver/grey • Atomic weight:40.078 • State: solid • Shells: 2-8-8-2 • Melting point: 842 degrees Celsius

  3. Where is Calcium Found? • 3rd most abundant metal • Accounts for 3.64% of earth’s crust • Never found free in nature • Easily forms compounds by reacting with oxygen and water

  4. Discovery of Calcium • 1808 Isolated b y Sir Humphrey Davy • Isolated through the electrolysis of a mixture of lime (CaO0 and mercuric oxide (HgO) • Electro-> electric current • Lysis-> Greek for release or break down

  5. Health and Calcium • Most abundant element in human body • Main constituent of bones • Essential in human skeleton and teeth • Body needs 2.5 g per day • Lack of calcium -> Osteoporosis • Glut of Calcium-> kidney stones, sclerosis of kidneys/blood vessels
