The vanderwaals radius of caesium is 343 pm(1*10 -12 m). Let us find out the radius of the caesium. The radius of a hypothetical hard sphere representing the separation between two atoms is known as the van der Waals radius. The boiling point of Caesium(Cs) is 671 ☌(1240 ☏) at 944 K. Let us find the boiling point of Caesium. The saturation pressure is the point at which boiling begins to happen for a specific temperature. The melting point of Caesium(Cs) is 28.5 ☌ (83.3 ☏) because of this melting point it is one of just five elemental metals with a liquid state at or close to room temperature. Let us check the melting point of Caesium. The temperature at which a substance transforms from a solid to a liquid. The atomic density of the caesium element is 1.873 g/cm 3. Let us find out the atomic density of Caesium. Caesium atomic DensityĪ measure is the number of atoms or nuclides per cubic centimetre (cm3) or per barn-cm. Despite being a reactive metal, it is thought to be the least electronegative element. Pauling scale determined that caesium had an electronegativity of 0.79. Let us check the value of electronegativity of Caesium. Caesium electronegativity according to PaulingĮlectronegativity means the measurement of an atom’s ability to attract a pair of bonding electrons. The atomic weight of the caesium(Cs) is 132.9 g/mol. Let us check the atomic weight of Caesium. The atomic weight is the ratio of a chemical element’s atoms’ average mass to a reference value. The atomic number(Z) of the caesium(Cs) atom is Z = 55. Let us check the atomic number of Caesium. Caesium atomic numberĪ nucleus’ atomic number is defined as its number of protons or electrons. Let us check from which block the caesium lie.Ĭaesium(Cs) element belongs to the s-block (Alkali metal group) of the periodic table. Caesium block in periodic tableīlock is a generic term for a collection of elements from the periodic table. Let us check to which period Caesium belongs.Ĭaesium(Cs) elements lie in the 6th period of the modern periodic table. In the periodic table, a period is a row of elements. ![]() In the periodic table Caesium(Cs) lie in group 1. ![]() Let us check the Group of Caesium belongs. In the periodic table, a group is a column of elements. Let us check the atomic symbol of Caesium.Ĭaesium(Cs) is represented with the symbol Cs in the periodic table. Caesium symbolĪ code is used to distinguish one element from another in the Periodic Table of Elements. Let us discuss some more chemical properties like melting point, boiling point, ionization energy, and oxidation state in detail below. It is having atomic number 55 u and a mass is 132.9 g/mol. Let us study some facts about Caesium.Ĭaesium(Cs) is an alkali metal element that belongs to the hydrogen family in the periodic table. Caesium(Cs) element also written as Cesium is a chemical element that belongs to the group 1st.
