In summary, particles are measured in units of mass, such as kilograms or atomic mass units, and their mass can also be calculated using size, density, and composition. The largest known particle is the Higgs Boson with a mass of approximately 125 GeV. Currently, there are no known particles larger than the Higgs Boson, but there may be undiscovered particles with a larger mass. The mass of particles can affect their behavior, such as their speed, gravitational pull, and interactions with other particles. Particles can also be smaller than atoms, with subatomic particles such as quarks and leptons making up protons and neutrons.

If you mean sub-atomic particles. One of the heavier ones are W+, W- and Z_0. These are vectorbosons and their mass is approx. 180,000 m_e (electron mass). Vectorboson are responsible for the electroweak forces.

Yes, sub-atomic or inter-stellar particles.
 

Related to How massive are the largest (dimensionally) particles?

1. How are particles measured in terms of mass?

Particles are measured in units of mass, such as kilograms (kg) or atomic mass units (amu). The mass of a particle can also be calculated using its size, density, and composition.

2. What is the largest known particle in terms of mass?

The largest known particle in terms of mass is the Higgs Boson, which has a mass of approximately 125 gigaelectronvolts (GeV) or 2.2 x 10^-25 kilograms.

3. Are there any particles that are larger than the Higgs Boson?

Currently, the Higgs Boson is the largest known particle. However, there may be other particles that have not yet been discovered that could have a larger mass.

4. How does the mass of particles affect their behavior?

The mass of a particle can affect its behavior in various ways. For example, particles with larger masses tend to move slower and have a greater gravitational pull. Mass can also determine how particles interact with each other.

5. Can particles be smaller than atoms?

Yes, particles can be smaller than atoms. Atoms are made up of smaller particles such as protons, neutrons, and electrons. There are also subatomic particles, such as quarks and leptons, that make up protons and neutrons.
