Caesium Properties Atomic Number of Caesium Caesium is a chemical element with atomic number 55 which means there are 55 protons and 55 electrons in the atomic structure. The strongest bond for a homonuclear diatomic species is that of dinitrogen, N 2 (945.33 ± 0.59 kJ mol -1). Caesium has physical and chemical properties similar to those of rubidium and potassium. The strongest bond for a diatomic species is that of carbon monoxide, CO (1076.5 ± 0.4 kJ mol -1). A note of caution: the strength of, say, the C-H bond in the gaseous diatomic species CH (not an isolable species) is not necessarily, the same as the strength of a C-H bond in, say, methane. You should consult reference 1 for further details.
Generally, these data were obtained by spectroscopic or mass spectrometric means. Kerr (University of Birmingham, UK) for the provision of the bond strengths of diatomic molecules data.
