If we go a little back in the future and go through history then the element Cesium was first discovered by a chemist who was in German Robert Bunsen and with him, one more individual was a physicist, Gustav Kirchhoff. We all must have heard and studied the Pauling scale, therefore Cesium Electron Configuration is also one of the most electronegative elements which have a value of 0.79 on the Pauling scale. It is pyrophoric and it also has the ability that at a temperature of −177 ☏, it can react with water, and apart from that one more benefit is that it is highly reactive with all other metals. The advantage of cesium that makes it different from other elements is that its physical and at the same time chemical properties are quite similar to potassium and rubidium. How Many Valence Electrons Does Cesium Have The melting point of cesium is 83.3 o F and if we convert it to Celsius form, then it will be written as 28.5 o C among the five elemental metals, cesium is one of the elements which are at room temperature. As we have already talked about the term electronic configuration but for those who are new here and are not aware of what electronic configuration is then it is the distribution of various electrons of a molecule in any molecular orbitals or atomic orbitals.Įvery element has its own Cesium Electron Configuration whereas here the electronic configuration for the element Cs is written as 6 s1. What is the Electron Configuration of Cesium?Ĭesium is one of the elements in chemistry, its atomic number is 55 and its symbol of it is written as ‘Cs”. Inside the table, there is an element named Cesium. We all must have needed a periodic table while we learn the basics of chemistry. It is not a very big task but one just has to practice it to learn the name. For those users who are still not aware of the full form then it stands for International Union of Pure and Applied Chemistry. Therefore, in the future, if one does not laugh at you, firstly it is important to know the full form of IUPAC. But if you ask them the full name of it then they will at first ask you that does it has a full name also? Or you can even expect to get answers like some odd one. Therefore, there are various non-equivalent definitions of atomic radius.Cesium Electron Configuration: (Caesium is the IUPAC spelling) If you have studied chemistry in your lower grades then you must have surely come across one term and that is IUPAC. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. It must be noted, atoms lack a well-defined outer boundary. The atomic radius of Caesium atom is 244pm (covalent radius). Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. Mass numbers of typical isotopes of Caesium are 133. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.įor stable elements, there is usually a variety of stable isotopes. Neutron number plus atomic number equals atomic mass number: N+Z=A. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10 -19 coulombs. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Atomic Number – Protons, Electrons and Neutrons in CaesiumĬaesium is a chemical element with atomic number 55 which means there are 55 protons in its nucleus.
