Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...
We are shown that the atomic number is the number of protons in an atom. We see that the mass number minus the atomic number is the number of neutrons. We complete the atomic structure by ...
Atomic and molecular physics it the study of the properties, dynamics and interactions of the basic (but not fundamental) building blocks of matter. A crucial component of this is understanding ...
