Which is not a representative particle? a) atom b)cation c)anion d)none of the above (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.he 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.

Charged particle Charged particle. In physics, a charged particle is a particle with an electric charge. It may be an ion, such as a molecule or atom with a surplus or deficit of electrons relative to protons. It can be the electrons and protons themselves, as well as other elementary particles, like positrons. It may also be an atomic nucleus devoid of electrons, such as an alpha particle, a helium nucleus. Neutrons have no charge. A plasma is a collection of charged particles, atomic nuclei and separated electrons, but can also be a gas containing a significant proportion of charged particles.

- DEFINITION of 'Representative Sample'. A subset of a statistical population that accurately reflects the members of the entire population. A representative sample should be an unbiased indication of what the population is like.

Particle size 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).he 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 `particle’ is a small mass at some position in space. 1. When the sum of the forces acting on a particle is zero, its velocity is constant; 2. The sum of forces acting on a particle of constant mass is equal to the product of the mass of the particle and its acceleration; 3.

Representation (politics) Under representative democracy, substantive representation (in contrast to descriptive representation) is the tendency of elected legislators to advocate on behalf of certain groups. Conflicting theories and beliefs exist regarding why constituents vote for representatives.

Grain size Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain. A single grain can be composed of several crystals. Granular material can range from very small colloidal particles, through clay, silt, sand, and gravel, to boulders.

Air Quality Index - A Guide to Air Quality and Your Health Particle Pollution (PM) Particle pollution, also called particulate matter or PM, is a mixture of solids and liquid droplets floating in the air. Some particles are released directly from a specific source, while others form in complicated chemical reactions in the atmosphere. Particles come in a wide range of sizes. Particles less than or equal to 10 micrometers in diameter are so small that they can get into the lungs, potentially causing serious health problems. Ten micrometers is less than the width of a single human hair. 1  Coarse dust particles (PM10) are 2.5 to 10 micrometers in diameter. 2  Fine particles (PM2.5) are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope.

- A suspension containing particles between 1 nm to 0.5 µm in size is called colloidal suspension. When the particle size is between 1 to 100 µm, the suspension is called coarse suspension.Most of the pharmaceutical suspensions are coarse suspension.he density of the vehicle of a suspension can be increased by adding the following substances either alone or in combination: polyethylene glycol, polyvinyl pyrolidone, glycerin, sorbitol, and sugar. The viscosity of the vehicle also affects the velocity of sedimentation.

Particle in a one-dimensional lattice Particle in a one-dimensional lattice. In quantum mechanics, the particle in a one-dimensional lattice is a problem that occurs in the model of a periodic crystal lattice. The potential is caused by ions in the periodic structure of the crystal creating an electromagnetic field so electrons are subject to a regular potential inside the lattice. This is an extension of the free electron model that assumes zero potential inside the lattice.

- Summary. A representative sample is demographically and characteristically similar to the population of interest. When the sample matches the population, it can be inferred that any effects shown by the sample are likely to be reflected in the population, too.

Deposition of Inhaled Particles in the Human Respiratory Tract and Consequences for Regional Targeting in Respiratory Drug Delivery Total deposition is the mean probability that an inhaled particle is deposited in the respiratory tract. Particles smaller than 0.1 μm in diameter are solely deposited due to diffusion (Figure 1) Figure 1. Total deposition of unit-density spheres in the human respiratory tract inhaled orally at rest.

- Fundamental Particles. A fundamental particle-also known as an elementary particle-is one that cannot be broken into smaller pieces. An atom is not a fundamental particle, because it consists of protons and neutrons in its nucleus and has a cloud of electrons orbiting the nucleus.

Mean free path In kinetic theory the mean free path of a particle, such as a molecule, is the average distance the particle travels between collisions with other moving particles. The formula still holds for a particle with a high velocity relative to the velocities of an ensemble of identical particles with random locations.
