The low melting point and softness of francium and cesium are a consequence of the size of their atoms.Īre there any elements that are liquids at room temperature?Īt this temperature and ordinary pressure, only two elements are liquids: Bromine (symbol Br and atomic number 35) and mercury (symbol Hg and atomic number 80) are both liquids at room temperature. What is the melting point of francium and cesium?Ĭesium (symbol Cs and atomic number 55), a soft metal that violently reacts with water, melts at 301.59 K. Caesium reacts explosively with cold water, and reacts with ice at temperatures above -116☌. Caesium, gallium, and mercury are the only three metals that are liquid at or around room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.Ĭonsidering this, what is Caesium state of matter at room temperature? Caesium: description It is silvery gold, soft, and ductile. It is a soft, silvery-golden alkali metal with a melting point of 28.5 ☌ (83.3 ☏), which makes it one of only five elemental metals that are liquid at or near room temperature. What is the melting point of caesium at room temperature? Cesium salts and most cesium compounds are generally very water soluble, with the exception of cesium alkyl and aryl compounds, which have low water solubility. Is cesium soluble in water?Ĭesium is a silvery white, soft, ductile metal with only one oxidation state (+1). This reaction is so fast, that if you tried pouring water into a test tube containing caesium (don’t do it), the glass container would shatter all over the place. When caesium makes contact with water, it reacts very rapidly, and forms a colourless solution of caesium hydroxide (CsOH) and hydrogen gas (H2). What is the state of matter of cesium at room temperature? Is Caesium a solid liquid or gas?Ĭlassified as an alkali metal, Cesium is a solid at room temperature. Basically, the atoms don’t share their electrons with nearby atoms, so it is easy to separate them from solids into liquids.Ĭesium is one of four metals that are liquid at or near room temperature the others are mercury (melting point of minus 37.9 F, or minus 38.8 C), gallium (melting point of 85.6 F, or 29.8 C) and francium (melting point of 80.6 F, or 27 C) according to Chemicool.
The reason these elements are liquids has to do with how tightly bound their electrons are to the atomic nucleus. They are francium, cesium, gallium, and rubidium (all metals). Why is cesium liquid at room temperature? It is liquid at room temperature and reacts explosively with cold water. Is cesium a solid liquid or gas at room temperature?Ĭesium is located in row 6 of the periodic table and is also an alkali metal. 4 What is the melting point of francium and cesium?.1 Is cesium a solid liquid or gas at room temperature?.
