You question makes no sense. If particles dissolve they go into solution, they do not "break apart and scatter".
It is called the solute. The substance doing the dissolving (often water) is the solvent.
The substance is broken to molecules or association of molecules.
This process is called dissolution.
Dispersion
In the preparation of colloids, using the dispersion method, larger particles of the substance are broken down into much smaller parts. Using the condensation method, smaller particles are dispersed and condensed to colloidal size.
Particles are smaller
When you break up a solid into smaller pieces it dissolves faster when you have big pieces of the solid you have to wait for the substance that is dissolving it ti be picked up by the object that is being dissolved but when the pieces are smaller it dissolves faster because their smaller and the substance dissolving the object get picked up much faster
An atom, these include protons, neutrons and electrons. The number of these smaller particles is what distingushes one atom of an element for another. For example, an atom of oxygen has 8 protons, neutrons, and electrons while a hydrogen atom has 1 proton neutron and electron
Smaller particles of rock are produced from larger particles.
The size of the particles of solute do not affect the solubility of a substance, which is determined by its chemical composition, but it does affect how quickly it dissolves. The smaller the particles of the solute, the faster it will dissolve.

Atoms
The solute is the name of the substance that dissolves in a solvent e.g. in salt water, salt is the solute, water is the solvent.
The smaller the particle the faster it dissolves. This is because the process by which a solute dissolves takes place at the surface of the solvent. That means the larger the surface area of a particle or solute, the faster the solute will dissolve.
The solvents particles (for example salt) break up into smaller pieces and they mix with the solute particles (for example water).
Mechanical digestion tears, grinds, and mashes large food particles into smaller ones.
if a substance has more particles in a smaller space (higher density), then the substance can be less easily displaced and has a higher upthrust
If you want to make materials dissolve faster, and your adding stuff to a drink, like lemonade, maybe you would cut up the little sugar cubes even smaller, so that the liquid has less to dissolve; and if you stir the drink after adding all the ingredients together, the particles will collide with each other and make the dissolving even faster. !
Table salt is made up of smaller clumps of particles than rock salt. To dissolve, particles of the salt must come in contact with the solvent particles than rock salt, resulting in faster dissolving. (Copied from the Pure Substance & Mixtures Section of some Nelson Literacy Science Text Book) :)
