Pro Lite, Vedantu Since the density (ρ) of a substance is the total mass (m) of that substance divided by the total volume (V) occupied by that substance, it is obvious, the density of a substance strongly depends on its atomic mass and also on the atomic number density (N; atoms/cm3). Cesium reacts violently with water and ice, forming cesium hydroxide (CsOH). The formula of the compound shows that there are three atoms of cesium for each atom of nitrogen. The size and mass of atoms are so small that the use of normal measuring units, while possible, is often inconvenient. Most materials expand when their temperatures increase. There are 3 other radioactive cesium isotopes that have atomic weights of 134, 135, and 137. (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. The Van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. Therefore the space in an atom (between electrons and an atomic nucleus) is not empty, but it is filled by a probability density function of electrons (usually known as  “electron cloud“). For example, 63Cu (29 protons and 34 neutrons) has a mass number of 63 and an isotopic mass in its nuclear ground state is 62.91367 u.
