These would include particles such as the constituents of atoms – protons, neutrons, and electrons – as well as other types of particles which can only be produced in particle accelerators or cosmic rays.

Feb 7, 2026 · Particle physics is concerned with structure and forces at this level of existence and below. Fundamental particles possess properties such as electric charge, spin, mass, magnetism, …

The theory describes two fundamental types of particles: fermions, which makes up all of the ‘stuff’ around us, and bosons, which mediate how fermions interact with one another.

May 26, 2025 · Particle physics describes the universe at the smallest scale. This includes subatomic particles, like protons and neutrons, as well as elementary particles, like quarks and electrons, which...

Aug 29, 2024 · Particles can be atoms, molecules, or subatomic particles like protons, neutrons, and electrons. These tiny units are the building blocks of all substances, both living and non-living. Atoms …

What is a particle? Classically, particles & waves are 2 different things. A classical particle is a point-like object. The type of particle is defined by properties that define how it interacts: mass (gravity) & …

Nov 12, 2020 · Given that everything in the universe reduces to particles, a question presents itself: What are particles? The easy answer quickly shows itself to be unsatisfying. Namely, electrons, …

Mar 26, 2025 · Elementary particle physics is the study of fundamental particles and their interactions in nature. Those who study elementary particle physics—the particle physicists—differ from other …

Normal matter is made of molecules, which are themselves made of atoms. Inside the atoms, there are electrons spinning around the nucleus. The nucleus itself is generally made of protons and neutrons …

Key points Almost everything is made of particles. Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases.
