This is a difficult question because size doesn't really apply to particle physics, even less when one considers particle-wave dualities. Of all the particles that can be considered as "matter", muon neutrinos (νμ) are currently understood as the lightest, with a mass of about 170 keV, or around 3.311 x 10-31 kilograms.
On the other hand, forces are also carried by (non-matter) particles, photons (mediate the electromagnetic force) and gluons (mediate the strong nuclear force) are both known to have zero mass.
observable ? i'd say quarks.
The more particle is given the less water would go through it leaving the particle wet
viruses are the smallest pathogens
roc is the smallest
the smallest adult is dwarfs.
The smallest particle of an element is called an atom.
An atom is the smallest particle of a substance.
The smallest particle of matter is called an atom. It consists of protons, neutrons, and electrons.
The smallest particle in the atom is the electron.
A Higgs-Boson particle.
An atom is a particle, the smallest particle that can exist by itself.
This particle is called atom.
If it is an element, then the smallest particle that retains the characteristics of the element is an atom. If it is a diatomic element, then the smallest particle that retains the characteristics of the element is a molecule. If it is a molecular compound, then the smallest particle that retains the characteristics of the compound is a molecule. If it is an ionic compound, the smallest particle that retains characteristics of the compound is a formula unit.
clay has the smallest particles
An atom is the smallest particle of a substance.
No, for all elements the smallest particle that can exist independently is an atom.
An electron has the smallest mass compared to a proton and a neutron.
