Isotope Notation for Bromine

This video tutorial explains how to write isotope notation, also known as nuclear notation, for bromine isotopes. It covers the two major isotopes of bromine, bromine-79 and bromine-81, and explains the difference between hyphen notation and nuclear notation. The video provides step-by-step instructions on how to write the nuclear notation for each isotope, including the placement of mass and atomic numbers. It also discusses how to calculate the number of neutrons in an isotope by using the mass number and atomic number.
