92Hydrogen-like atom — A hydrogen like atom is an atom with one electron and thus is isoelectronic with hydrogen. Except for the hydrogen atom itself (which is neutral) these atoms carry the positive charge e(Z 1) , where Z is the atomic number of the atom. Examples of …
93Quantum chemistry — is a branch of theoretical chemistry, which applies quantum mechanics and quantum field theory to address issues and problems in chemistry. The description of the electronic behavior of atoms and molecules as pertaining to their reactivity is one …
94Rutherford scattering — In physics, Rutherford scattering is a phenomenon that was explained by Ernest Rutherford in 1911,[1] and led to the development of the Rutherford model (planetary model) of the atom, and eventually to the Bohr model. It is now exploited by the… …
95Nuclear chemistry — is the subfield of chemistry dealing with radioactivity, nuclear processes and nuclear properties. It is the chemistry of radioactive elements such as the actinides, radium and radon together with the chemistry associated with equipment (such as… …
96Nonradiation condition — Classical nonradiation conditions define the conditions according to classical electromagnetism under which a distribution of accelerating charges will not emit electromagnetic radiation. According to the Larmor formula in classical… …
97Positronium — (Ps) is a system consisting of an electron and its anti particle, a positron, bound together into an exotic atom . Being unstable, the two particles annihilate each other to produce two gamma ray photons after an average lifetime of 125 ps or… …
98Magnetic monopole — It is impossible to make magnetic monopoles from a bar magnet. If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. Inst …
99Phenomenology (science) — The term phenomenology in science is used to describe a body of knowledge which relates several different empirical observations of phenomena to each other, in a way which is consistent with fundamental theory, but is not directly derived from… …
