Protons, Neutrons and Electrons Explained - what's the difference?

This video tutorial explores the three subatomic particles: protons, neutrons, and electrons. It explains their roles in the atom, including how protons determine the element's identity, neutrons affect atomic mass and create isotopes, and electrons influence chemical reactivity and charge. The video also discusses the implications of changing the number of these particles, such as altering the element, mass, or charge, and provides a summary of these concepts.
