    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.

    If an isotope has a +2 charge, as with strontium (atomic number 38), then the number of electrons is two less than the number of protons. In this case, the calculation becomes 38+(-1)(+2)=38-2=36, so the ion has 36 electrons. The usual shorthand for ions shows the charge imbalance as a superscript following the atomic symbol.
