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.

The large amount of energy imparted upon it in a particle accelerator.
Greater density causes particles to settle faster.
When light strikes particles larger than its wavelength, it scatters in all directions. This is known as Mie scattering, which differs from Rayleigh scattering that occurs with smaller particles. Mie scattering causes light to lose intensity and change direction as it interacts with the larger particles.
All states of matter have vibrating particles, but solids' particles vibrate only.
Heat energy from the source causes the particles to oscillate (vibrate) this chains and causes neighbouring particles to vibrate.
The movement of particles that causes mixing is called diffusion. It is the process by which particles move from an area of high concentration to an area of low concentration, resulting in a more uniform distribution of the particles.
When one part of a vibration causes air particles to spread out, they form ararefaction
Two new isotopes are produced by fission.
When an eraser is rubbed against paper, the friction between the eraser and the paper causes small particles of the eraser to break off. These particles stick to the paper, leaving a mark and making the eraser appear to shrink in size. This process is known as abrasion.
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
Thermal energy causes particles to vibrate. When thermal energy is transferred to an object, its particles gain kinetic energy, causing them to move and vibrate.
Particles in matter move back and forth due to thermal energy, which causes them to vibrate. This vibration is a result of the kinetic energy of the particles constantly changing direction.
