__**Physical Properties**__

 * Soft, silvery-white metal
 * Melting Point of 6 3 o C
 * Boiling Point of 7 70 o C
 * Density is 0.862 grams per cubic centimeters
 * Less than the density water
 * Potassium can float of water
 * Melting point is low for a metal; it will melt under flame of a candle

__**Chemical Properties**__

 * Potassium forms many compounds
 * Potassium is highly reactive
 * Reacts with water violently & gives off hydrogen gas
 * The hydrogen gas creates a purple flame and may explode
