Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes of an element have the same atomic number but different mass numbers. For example, hydrogen has three isotopes: protium, deuterium, and tritium.
Here are some key concepts to focus on when studying isotopes:
By understanding these key points and concepts, you will develop a strong foundation in the topic of isotopes and their significance in the study of chemistry and beyond.
