The discussion centers on the correlation between the size of matter particles, defined as their de Broglie wavelength, and their mass. It is established that the de Broglie wavelength is inversely related to momentum, which is a product of mass and velocity. Participants clarify that elementary particles, such as electrons, are considered point-like and do not possess a defined size. Ultimately, the consensus is that there is no direct correlation between particle size and mass.
PREREQUISITESPhysicists, students of quantum mechanics, and anyone interested in the fundamental properties of particles and their behavior in the realm of particle physics.

How else to consider particle size?weirdoguy said:And what do you mean by "matter wavelength" and why should it be considered as particles size? If it's de Broglie wavelength then just check the formula for it.
Since de Broglie wavelength = h/momentum = mass x velocity, that would give us an indirect sense of the ‘size‘ of the particle, in relation to its mass.weirdoguy said:Well, elementary particles (like electron) are considered to be point-like, that is, they don't have size.
