Definition & Meaning of Subatomic Particles
Subatomic particles are the fundamental building blocks of matter, existing within atoms. They are smaller than atoms and are primarily classified into three categories: protons, neutrons, and electrons. Each of these particles has distinct properties and roles in the structure of an atom.
Protons carry a positive charge and are located in the nucleus of an atom. Neutrons are neutral and also reside in the nucleus, contributing to the atomic mass. Electrons are negatively charged particles that orbit the nucleus in various energy levels.
The arrangement and interaction of these subatomic particles determine the chemical properties of elements and their behavior in reactions. Understanding subatomic particles is crucial for fields such as chemistry, physics, and materials science.
