Bananas are radioactive but so is basically everything we eat. .01 percent of potassium atoms are radioactive isotope k40. Potassium explodes in water with purple flames. It's critical to nerve transmission to low and fingers will freeze in place and deadly if deficiency reaches the heart. Potash is a common fertilizer potassium carbonate and potassium sulfate. Sodium free salt potassium chloride. Bright and shiny when not oxidized. |

Calcium |
The stone.called.chalk. In the cliffs of Dover is calcium carbonate chalk if the blackboard variety is calcium sulfate known as gypsum. The element is.a.shiny metal. It's unstable in air. When in contact with water or.acid it produces hydrogen gas in small amounts. Rigid hydroxyapetite foam a form.of.hydrated calcium phosphate this is bones. It's constantly moving in and out of cells. Used to inflate weather balloons |
