A particle diagram is a graphic representation of the particles that make up a substance. In the diagram, each particle is represented by a symbol or a shape. The symbols or shapes can be used to show the type of particle. For example, circles can represent atoms, while squares can represent molecules. In a particle diagram, the particles are ...

Electrons are one of three main types of particles that make up atoms. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles. They are a type of fundamental particle called leptons. All leptons have an electric charge of (-1) or (0).

Under normal conditions, there are three distinct states of matter: solids, liquids, and gases. Solids are relatively rigid and have fixed shapes and volumes. A rock, for example, is a solid. In contrast, liquids have fixed volumes but flow to assume the shape of their containers, such as a beverage in a can. Gases, such as air in an automobile tire, have …
