These particles are: proton and neutron.
The most basic answer would be that they dont have the same properties as the bulk material and these particles in the nm size range are governed by quantum mechanics.
If the particles in a substance are moving, the volume of that substance becomes larger because the particles move faster and spread farther appart. the mass of the object stays the same because it is the same amount of particles, just in a format in which the volume is larger. hope i helped :)

Two particles that have a charge of the same sign - that is, either two positive particles, or two negative particles.
round particles of the same size.
becuz the particles don't move

Sand particles are in fact a variety of sizes on the same beach front. This is because these sand particles are formed at different times through different processes.
Liquids cannot stay the same size size because the particles inside the liquids have some bit of space to move to a different shape and to change the size.
Subatomic particles are the same size as basketballs.
Round particles of the same size, as in pure quartz sand.
No. The spaces between the particles in a gas are much bigger than the particles themselves. The size of a particle does not vary between the states of a substance.
