What are Isotopes?

The video explains that elements have the same atomic number, meaning they have the same number of protons. However, they can have different mass numbers due to varying numbers of neutrons, leading to isotopes. Isotopes are atoms of the same element with different masses but identical chemical properties. The video uses carbon-12 and carbon-14 as examples to illustrate isotopes, showing how they differ in neutron count. It also mentions other isotopes like hydrogen and chlorine, emphasizing that isotopes share chemical properties because neutrons do not affect chemical behavior.
