Topic: Isotopic Notation

CHEMDUNN ·

2025/08/18

Every element has a unique identity, but what about its different "versions"? In this episode, we're cracking the code of isotopic notation, the shorthand chemists use to describe an atom's specific makeup. You'll learn how to read and write these symbols, understanding what the atomic number (the number of protons) and the mass number (protons plus neutrons) tell us about an atom. Get ready to uncover the hidden details of atoms and understand their true individuality!
