most reactive elements on the periodic table

Exposure to radioactivity is never healthy and can have dire effects, including cancer. Nuclear power plants and nuclear weapon testing can release this radioactive isotope. It dissolves easily in water and binds to the soil, which then contaminates growing plants. While low levels of this element exist in the air, radioactive cesium has also been identified in both surface water and foods. It behaves similarly to sodium, as it reacts well with chlorides to form a crystalline powder. How dangerous is cesium?Īs stated, Cesium-137 is a radioactive isotope that comes from nuclear fission. Does an element seemingly as dangerous and spontaneous as cesium have any use? Let’s find out.

This results in the formation of superficial superoxide, which can be harmful. Additionally, the metal oxidizes rather quickly from air exposure. It also explodes when it reacts with cold water. This element is sensitive to moisture and may explode in your hands. While this sounds interesting, do NOT hold it. The metal will melt in your hands, into a candle wax-like consistency. It has a very low melting point of 28.5˚C (83.3˚F), which is just above room temperature. The element cesium is the softest of all the metals. The Element Cesium is a softy (but beware!) Is cesium a metal? It has the largest atomic radius, and the smallest electronegativity, of all the stable elements. It lies below the element rubidium and above francium in group 1 of the periodic table, the alkali metals. Cesium is the most reaction metal on the periodic table that is stable.Ĭesium has atomic symbol Cs, and atomic number 55. If the reaction of cesium metal and water takes place in a glass bottle, the bottle will shatter.About 27 kg of radioactive cesium-137 contaminated the air as a result. Due to flawed design and deviation from safety regulations, the nuclear power plant exploded. The Chernobyl Accident of 1986 took place at the Chernobyl nuclear power station in Ukraine.Theoretically, 1 kg of cesium can force a vehicle 140 times as far as the burning of the same amount of any liquid or solid. These metals include gallium and mercury. Only two other metals, in addition to cesium, are liquid at or near room temperature.The element cesium is the most electropositive and alkaline element on the periodic table.The name cesium comes from the Latin word “caesium”, which means “sky blue”.It is one of just four metals that are liquid at or near room temperature. Out of all the metallic elements, cesium has the second lowest melting point.Cesium was the first element to be discovered through spectroscopy.Let’s learn more about this exciting, spontaneous element. It is also one of only 5 metals that can be a liquid in a warm room. It is one of the most reactive metals on Earth It is extremely reactive and highly-flammable. This element is shiny and has a silvery-goldish finish. The element cesium belongs to the alkali metal group, or Group 1, of the periodic table.
