WebPotassium is one of the alkali metals. The alkali metals are the elements that make up Group 1 (IA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to one another. The alkali metals also include lithium, sodium, rubidium, cesium, and francium. They are among the most active metals. WebPotassium iodide is an inorganic chemical compound which is denoted by the chemical formula KI. Potassium iodide is a metal-halide salt featuring an ionic bond between the potassium cation (K+) and the iodide anion (I–). It is colourless to white, it appears as cubical crystals, or powder or white granules. It has a highly bitter, saline taste.
