  1. Calcium Cherlyne Wang 9 Ivory

  2. Group 2 in the Periodic Table

  3. Occurrence and Method of Extraction • Calcium is not naturally found in its elemental state. • Its method of extraction is electrolysis of molten ores. Reactivity series for metals

  4. Chemical Properties

  5. Physical Properties

  6. Reactions • Once produced, it rapidly forms a gray-white oxide and nitride coating when exposed to air. • When lit, the metal burns in air with a brilliant high-intensity orange-red light. • It reacts with water, generating hydrogen gas at a rate rapid enough to be noticeable, but not fast enough at room temperature to generate much heat, making it useful for generating hydrogen. • In powdered form, the reaction with water is rapid, as the increased surface area of the powder accelerates the reaction with the water.

  7. Calcium is used as a reducing agent in order to extract metals such as uranium, zirconium and thronium • Cheeseis made using calcium ions to promote the coagulation of milk. • Cement and mortar, important when constructing buildings and other things, are made using calcium.
