Three isotopes of carbon are represented using nuclide notation as follows:
612P,613Q,614R ^{12}_6\text{P}, \quad ^{13}_6\text{Q}, \quad ^{14}_6\text{R} 612P,613Q,614RDescribe how this nuclide notation shows that each isotope is of the same element.
Describe how this nuclide notation shows the differences between these isotopes.
Radioactive isotopes emit radiation when they decay. State the names of three types of nuclear radiation.
