Isotopic mass

The video tutorial explains isotopes, which are variants of elements with different numbers of neutrons, leading to different relative atomic masses. It highlights that the atomic mass numbers in the periodic table are weighted averages of isotopic masses. Using copper as an example, the video illustrates how its relative atomic mass is calculated based on its two main isotopes, copper 63 and copper 65.
