Caesium atoms have 55 electrons and the shell structure is 2.8.18.18.8.1. The ground state electronic configuration of neutral caesium is Xe. 6s1 and the term symbol of caesium is 2S1/2. Chemical elements listed by atomic number The elements of the periodic table sorted by atomic number. Click on any elements name for further chemical properties, environmental data or health effects. This list contains the 118 elements of chemistry. Caesium or cesium is a chemical element with symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal with a melting point of 28 °C (82 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Cesium isn't a heavily used element. Salts of cesium form the basis for highly accurate atomic clocks, and they are also used as dense, environmentally friendly liquids for drilling in oil wells. Provided by the element sponsor Frances Separovic CESIUM Element symbol: Cs Atomic number: 55.

Atomic Number of Caesium is 55.

Chemical symbol for Caesium is Cs. Number of protons in Caesium is 55. Atomic weight of Caesium is 132.905452 u or g/mol. Melting point of Caesium is 28,4 °C and its the boiling point is 690 °C.

About Caesium

Caesium is a soft metal of yellowish color, which is very highly reactive and can explode in water. The name of this chemical element is derived from a Latin word meaning blue flames which can be seen when this element burns. This element can be found in minerals and is stored in oil as it is very highly reactive. Caesium has no biological importance and in its pure form is not toxic or poisonous. The most common use of this element is producing so called Caesium clock, which is an atomic clock with extremely high precision. Such clocks are used for GPR connections and mobile networks. Other applications of caesium and its compounds include optical glass producing, producing drilling fluids, as well as being used as a catalyst in chemical industry.

Uses of Caesium

Caesium (Cs), also known as Cesium, is used in photoelectric cells, vacuum tubes, scintillation counters, spectrophotometers, atomic clocks (caesium clocks), and photomultiplier tubes. It can be also used in thermionic power converters. In addition, Caesium is employed as an industrial gamma-ray source. Caesium carbonate, a compound with the formula Cs2CO3, is used in organic synthesis as well as in energy conversion. Caesium oxide, consists of caesium and oxygen, is exploited in devices like vacuum photodiodes and TV camera tubes. Caesium sulfate, another compound with the formula Cs2SO4, is employed for preparing dense aqueous solutions for use in isopycnic centrifugation.

Hp helio g85. We remember from our school chemistry course that every element has its own specific atomic number. It is the same as the number of protons that the atom of each element has, so sometimes atomic number is called proton number. It is always the whole number and it ranges from 1 to 118, according to the number of the element in the Periodic Table. This number can be really important and something essential to know, in relation to a certain chemical element which is the issue of our interest at the moment.

Why is this so? Why is the atomic number so important? First of all, it is the number that makes elements different from one another as it shows the number of protons in their nuclei. Also, knowing the atomic number of an element can give us an idea about the position of the element in the Periodic Table. Atomic number of an element never changes: for example, the atomic number of oxygen is always 8, and the atomic number of Chlorine is always 18. The atomic number is marked with the symbol Z, taken from a German word zahl (or atomzahl, which is 'atomic number' in German).

This website is created for those who need to know the atomic number of a central chemical element. By using our website, you can do it in just one click and receive short and correct information on this matter. There is also some extra summary on every each chemical element which can be found at our website, including the atomic weight of each element, as well as physical and chemical properties of every element and its importance. Use this website at any time when you need to get fast and precise information about atomic or proton number of chemical elements.
