They are called sub-atomic (or subatomic) particles ... some of the most common ones are named protons, neutrons, electrons, positrons, mesons, antimesons, neutrinos, antineutrinos, and quarks.
It is made out of small particals, smaller than atoms called electrons.
A particle smaller than atom is a subatomic particle, protons , neutrons, and , electrons, the smallest one is an electron, smaller than that are point particles and elementary particles, one elementary particle and point particle is a quark, up quarks down quarks the smallest single thing found so far is a GLUON, which is the force which binds/holds quarks together. Where the devil lives in anti matter there are also atoms and subatomic particles and point particles but just anti, anti- GLUON, anti-QUARK, anti-ATOM, anti-SUBATOMIC PARTICLE. There is something called the string theory, and super string theory that theorizes about bosonic/boson strings but it can not be provine yet, and I think a gluon is still alot smaller than a bosonic/boson string if they are true. HOPE THIS HELPS
Yes, sand has fine particals, gravel is much larger.
The Universe was never smaller than an atom.
it can get smaller than an atom
An atom is smaller than a compound because if an electron fits in an atom, and an atom is a part of a compound, it means a compound is bigger than an atom
A proton is smaller than a molecule, which is a group of atoms bonded together. The nucleus is smaller than both a molecule and an atom, as it is the central part of an atom where most of its mass is concentrated.
There are a few substances smaller than the atom, they're called sub-atomic particles and include things like protons, neutrons, electrons, photons, quarks etc.
Smaller
Because they are much smaller than an atom
