What are protons, neutrons, and electrons?

Protons, neutrons, and electrons are the three main subatomic particles that make up an atom. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus in energy levels. The number of protons determines the element's identity, while the sum of protons and neutrons gives the atomic mass. Understanding the structure of atoms and the roles of these particles is crucial in the field of chemistry and helps us comprehend the building blocks of matter.
