Single Idea 21206
[filed under theme 27. Natural Reality / B. Modern Physics / 4. Standard Model / c. Particle properties
]
Full Idea
In quantum theory, the full set of quantum numbers defines the state of the particle and, along with its mass, determines its properties.
Gist of Idea
The properties of a particle are determined by its quantum numbers and its mass
