elementary particle
C2Formal, Academic, Technical
Definition
Meaning
A fundamental constituent of matter that is not composed of smaller particles.
In physics, a subatomic particle with no known substructure, such as an electron or quark, that serves as a basic building block of the universe.
Linguistics
Semantic Notes
The term is almost exclusively used in the context of particle physics. It often implies categorization within the Standard Model of particle physics.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation as 'начальная частица' or 'основная частица'. The standard Russian equivalent is 'элементарная частица'.
Common Mistakes
- Confusing with 'atom' or 'molecule'.
- Using plural 'elementary particles' incorrectly as a singular noun (e.g., 'An elementary particles...').
- Misspelling as 'elementry particle'.

Frequently Asked Questions
No, an atom is composed of a nucleus (itself made of protons and neutrons) and electrons. Protons and neutrons are composite particles (made of quarks), while electrons are elementary particles.
They are largely synonymous in modern physics, though 'fundamental particle' can sometimes have a broader philosophical connotation.
Not directly with the naked eye or ordinary microscopes. Their existence and properties are inferred through complex experiments in particle accelerators and detectors.
Yes, according to the Standard Model, there are several types: quarks (6 flavours), leptons (like the electron, 6 types), and force-carrying gauge bosons (like the photon and gluon).
