Subatomic Particles and Their Properties

This video tutorial introduces the three subatomic particles: protons, neutrons, and electrons. It explains their relative charges, with protons having a charge of +1, neutrons being neutral, and electrons having a charge of -1. The video also covers the relative mass of these particles, noting that protons and neutrons have a mass of 1, while electrons have a much smaller mass. The location of these particles is discussed, with protons and neutrons found in the nucleus and electrons in orbitals. Finally, the video explains how the balance of protons and electrons affects the charge of an atom, leading to the formation of ions.

What does the term 'subatomic' refer to?
