A representative particle is the type of particle that the substance is usually composed of. Representative particles are thus smallest units that have the same composition as the bulk material.
Particles are probably one of the most difficult and confusing aspects of Japanese sentences. A particle (joshi) is a word that shows the relationship of a word, a phrase, or a clause to the rest of the sentence. Some particles have English equivalents. Others have functions similar to English prepositions, but since they always follow the word or words they mark, they are post-positions. There are also particles that have a peculiar usage which is not found in English. Most particles are multi-functional. (Answer #1). A representative particle is the type of particle that the substance is usually composed of. Representative particles are thus smallest units that have the same composition as the bulk material. One mole consists of Avogadro's number of representative particles of that material. The representative particle of an element is an atom. The representative particle of a molecular compound is a molecule. The representative particle of an ionic compound is its formula unit. One formula unit of an ionic compound is composed of a cation and an anion. Therefore, cations and anions are the representative particles of ionic compounds. Thus, atoms, cations, anions-all are representative particles Formula Unit. The representative particle of an ionic compound is the formula unit. A formula unit uses a formula to calculate the basic whole number ratio of the ions in an ionic compound. Atoms are the smallest particle that can be split. Substances that contain only one kind of atom are called elements. A representative particle is the smallest unit of a substance that can be broken down without altering the composition. Matter is composed of three types of representative particles: atoms, molecules and formula units. Atoms are the smallest particle that can be split. Substances that contain only one kind of atom are called elements. A kernel of corn might be the representative particle for that grain crop. A grain of salt might be the representative particle for granular salt as a market commodity. These are important because of considerations regarding density and close packing and voids in bulk quantities of each commodity. A certain particle of given mass and energy might be the representative particle for, say, the study of particle beam divergence. It is used just like the term atom is the smallest representative particle of an element or a molecule is the smallest representative particle of a molecular compound. 1 mol of an ionic compound would contain 6.02 x 10 to the 23rd formula units.

The notion of particle size applies to colloidal particles, particles in ecology, particles present in granular material (whether airborne or not), and particles that form a granular material (see also grain size). The particle size of a spherical object can be unambiguously and quantitatively defined by its diameter. However, a typical material object is likely to be irregular in shape and non-spherical. A representative particle is thought of as the smallest unit into which a substance may be divided without changing its composition. Some examples might be helpful. For a given chemical element, it's an atom. A certain particle of given mass and energy might be the representative particle for, say, the study of particle beam divergence.
