Caesium Atomic Number Atomic Mass Density of Caesium

Atomic Mass of Caesium. Atomic mass of Caesium is 132.9055 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10-24 grams.

Radiation Activity and Intensity nde-ed

Activity The strength of a radioactive source is called its activity, which is defined as the rate at which the isotope decays. Specifically, it is the number of atoms that decay and emit radiation in one second. Radioactivity may be thought of as the volume of radiation produced in a given amount of time.

Radioactivity. Radioactive Decay Converter

Different types of radioactive decay include alpha, beta, and gamma decay. They are named after the particles emitted during this process. During the decay the radioactive particles take the energy away from the nucleus. Some radioactive decay changes the original nucleus of the atom into either a different nucleus or a nucleus in a changed state.
