WebCesium, gallium, and mercury are the only three metals that are liquid at room temperature. Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116C. Cesium hydroxide, the strongest base known, attacks glass. Uses. Because of it has great affinity for oxygen, the metal is used as a "getter" in electron tubes. Of all elements that are solid at room temperature, caesium is the softest: it has a hardness of 0.2 Mohs. It is a very ductile, pale metal, which darkens in the presence of trace amounts of oxygen. When in the presence of mineral oil (where it is best kept during transport), it loses its metallic lustre and takes on a duller, grey appearance. It has a melting point of 28.5 °C (83.3 °F), making it one of th…
WebOct 1, 2024 · Gallium is one of five elements with a melting point near room temperature. The other four are mercury, cesium, rubidium and francium. Gallium expands as it freezes like water. Gallium does not exist free in nature. Gallium is obtained as a byproduct in the production of zinc and aluminum. Most gallium produced today is used in electronics. WebJan 17, 2024 · Gallium easily melts on our hand because its melting temperature is well below our body temperature. Mercury is already a liquid at room temperature.
