Like charges repel

Electrostatics is the study of interactions between charged objects. Electrostatics alone will not described molecular systems, but it is very important to the understanding of interactions of electrons, which is described by a wave function or electron density. The central pillar of electrostatics is Coulombs law, which is the mathematical description of how like charges repel and unlike charges attract. The Coulombs law equations for energy and the force of interaction between two particles with charges q and q2 at a distance rn are... [Pg.8]

All of the material in this text and most of chemistry generally can be understood on the basis of what physicists call the electromagnetic force Its major principle is that opposite charges attract and like charges repel As you learn organic chemistry a good way to start to connect structure to properties such as chemical reactivity is to find the positive part of one molecule and the neg ative part of another Most of the time these will be the reactive sites... [Pg.16]

All of the forces in chemistry except for nuclear chemistry are electrical Opposite charges attract like charges repel This simple fact can take you a long way... [Pg.58]

The charge on a species has a major effect on its ability to donate or accept protons. Remember that opposite electrical charges attract, and like charges repel. An anion is both a better proton acceptor and a poorer proton donor than is a neutral molecule. Likewise, a cation is a poorer proton acceptor and a better proton donor. [Pg.1248]

This is exactly the same as the experimental rate law. It is reasonable that the first step be slow since it involves two negatively charged species coming together. We know that like charges repel, and thus this should not be an easy or rapid process. [Pg.339]

But time is money. The waste industry, therefore, breaks the colloid artificially to remove the particulate solid from the water. They employ one of two methods. Firstly, they add to the water an inorganic polymer such as silicate. The colloid s thermodynamic stability depends on the surface of its particles, each of which has a slight excess charge. As like charges repel (in consequence of Coulomb s law ... [Pg.513]

Unlike charges attract and like charges repel each other, so there is a high concentration of counterions attracted to the particle surface whilst co-ions (those with the same sign charge as that of the surface) are repelled. Thermal motion, i.e. diffusion, opposes this local concentration gradient so that the counterions are in a diffuse cloud around the particle. Of course particles which have a like charge will also repel each other but the interaction of the particle surfaces will be screened by the counterion clouds between the particles. The interaction potential is a function of the surface potential, i]/o, and the permittivity of the fluid phase, e = r80, where r is the relative permittivity.12,27... [Pg.53]

High-energy beams involving the above particles are created in particle accelerators, in which a charged particle is drawn forward by an electro-sfafic field wifh a charge opposite that of the particle (like charges repel one another, opposites attract) as the particle passes the source of each field, the charge of fhe field is reversed so that the particle is now pushed onto another field source. [Pg.17]

An alpha particle undergoes an acceleration due to mutual electric repulsion as soon as it is out of the nucleus and away from the attracting nuclear force. This is because it has the same sign of charge as the nucleus. Like charges repel. [Pg.685]

Atoms are bound into molecules by shared pairs of electrons. Electrons dislike each other because like charges repel each other. Therefore, whether they are lone pairs of electrons or bonding pairs of electrons, electron pairs try to get as far apart in space as is geometrically possible. There is a fancy name that summarizes these simple ideas the VSEPR theory, which stands for Valence Shell Electron Pair Repulsion Theory. Even though the VSEPR theory is founded on fundamentally simple ideas, it is a tremendously powerful tool for predicting the shapes of molecules. [Pg.161]

Charge is a quantized property of non-neutral matter. Charge can be positive or negative. Like charges repel and unlike charges attract. Electrical... [Pg.403]

Because water molecules are polar, they interact electrically (you know, like charges repel and unlike charges attract) with other molecules. For example, when you put sodium chloride (table salt) in water, the attraction between different parts of the water molecule and the ions that make up sodium chloride are strong enough... [Pg.73]
