Cesium properties

Cesium belongs to the group of alkali metals. This group of elements are characterized by having a single electron in its outermost energy level and have a tendency to lose it, thus forming a monopositive ion. This tendency of alkali metals such as cesium is due to their low ionization energy and low electronic affinity.

The state of cesium in its natural form is solid. Cesium is a gold-plated chemical element and belongs to the group of alkali metals. The atomic number of cesium is 55. The chemical symbol for cesium is Cs. The melting point of cesium is 301.59 degrees Kelvin or 29.44 degrees Celsius or degrees centigrade. The boiling point of cesium is 944 degrees Kelvin or 671.85 degrees Celsius or degrees Centigrade.

Atomic Properties of Cesium

The atomic mass of an element is determined by the total mass of neutrons and protons that can be found in a single atom belonging to this element. As for the position where to find cesium within the periodic table of elements, cesium is in group 1 and period 6. Cesium has an atomic mass of 132.90545 u.

The electron configuration of cesium is [Xe] 6s1. The electronic configuration of the elements determines the way in which the electrons are structured in the atoms of an element. Cesium’s mean radius is 260 pm, its atomic radius or Bohr radius is 298 pm, its covalent radius is 225 pm, and its Van der Waals radius is 343 pm. Cesium has a total of 55 electrons whose distribution is as follows: In the first shell it has 2 electrons, in the second it has 8 electrons, in its third shell it has 18 electrons, in the fourth, 18 electrons, in the fifth shell it has 8 electrons and in the sixth, 1 electron.
