PHYSICS - What Are Radioactive Isotopes - Properties of Matter

The video explains why atomic masses aren't whole numbers, focusing on isotopes and their role in atomic structure. It discusses how protons and neutrons determine an atom's identity and stability, with neutrons acting as nuclear glue. Isotopes, which have varying neutron numbers, are common in heavy elements. The video highlights hydrogen isotopes and their stability, explaining radioactive decay and its applications in medicine and chemistry. It concludes with a summary of isotopes' importance in science.
