The only isotope video you need to watch

This video tutorial explains isotopes, which are variations of the same element with different masses due to differing numbers of neutrons. It covers the basic concepts of atomic structure, including protons, neutrons, and electrons, and how these relate to isotopes. The video provides examples using sodium and carbon isotopes, illustrating how the number of neutrons changes while the number of protons remains constant, resulting in different mass numbers. The tutorial emphasizes the importance of understanding atomic notation and encourages viewers to review related topics for a comprehensive understanding.

What must remain the same for an element to be considered the same, even if its mass changes?
