Another way to represent different isotopes is called isotopic notation, or nuclear notation. This type of notation involves writing the chemical symbol for the element, and then writing the mass number as a superscript to the left of the symbol, and the atomic number (no. of protons) as a subscript to the left of the symbol. For example, carbon-12 is written as $\text{_6^12"C}$, and carbon-14 is written as $\text{_6^14"C}$.
