| Bohr's atom | A concept or model of the atom in which the negatively charged electrons move in circular or elliptical orbits around the positively charged nucleus, energy being emitted or absorbed when electrons change from one orbit to another. (05 Mar 2000) |

| Bohr, Christian | <person> Danish physiologist, 1855-1911. See: Bohr effect, Bohr's equation. (05 Mar 2000) |
|---|---|
| Bohr effect | <physiology> Decrease in oxygen affinity of haemoglobin when pH decreases or concentration of carbon dioxide increases. (18 Nov 1997) |
| Bohr, Neils | <person> Danish physicist and Nobel laureate, 1885-1962. See: Bohr's atom, Bohr magneton, Bohr's theory. (05 Mar 2000) |
| Bohr's equation | An equation to calculate the respiratory dead space from the fact that gas expired from the lungs is a mixture of gas from the dead space and gas from the alveoli, i.e., the dead space volume divided by the tidal volume equals the difference between alveolar and mixed expired gas composition, divided by the difference between alveolar and inspired gas composition; gas composition can be expressed in any consistent units of concentration or partial pressure of oxygen or carbon dioxide. (05 Mar 2000) |
| Bohr's theory | That spectrum lines are produced 1) by the quantised emission of radiant energy when electrons drop from an orbit of a higher to one of a lower energy level, or 2) by absorption of radiation when an electron rises from a lower to a higher energy level. (05 Mar 2000) |
| activated atom | An atom possessing more than normal energy as a result of input of energy. See: excited state. Synonym: excited atom. (05 Mar 2000) |
| atom | <chemistry, physics, radiobiology> A particle of matter indivisible by chemical means. It is the fundamental building block of the chemical elements. The elements, such as iron, lead and sulphur, differ from each other because they contain different kinds of atoms. There are about six sextillion (6 followed by 21 zeros or 6 x 1021) atoms in an ordinary drop of water. According to present day theory, an atom contains a dense inner core (the nucleus) and a much less dense outer domain consisting of electrons in motion around the nucleus. Atoms are electrically neutral. (16 Dec 1997) |
| radioactive atom | <chemistry, physics> An atom with an unstable nucleus, which emits particulate or electromagnetic radiation (radioactive emission) to achieve greater stability. See: radionuclide, half-life, Becquerel. (05 Mar 2000) |
| recoil atom | The remainder of an atom from which a nuclear particle has been emitted or ejected at high velocity; the remainder recoils with a velocity inversely proportional to its mass. (05 Mar 2000) |
| central atom | <physics> The atom to which the other atoms are bonded in a small molecule. (09 Oct 1997) |
| spectrometry, mass, fast atom bombardment | A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information. (12 Dec 1998) |
| stripped atom | An atom minus all its electrons; a nucleus. (05 Mar 2000) |
| nuclear atom | <physics, radiobiology> A concept or model of the atom characterised by the presence of a small, massive nucleus at its centre. (05 Mar 2000) |
| displacements per atom | (dpa) This is a measure of the amount of radiation damage in neutron-irradiated materials, for example, 10 dpa means each atom in the material has been displaced from its site within the structural lattice of the material an average of 10 times (due to interactions between the atoms and the energetic neutrons irradiating the material.) (09 Oct 1997) |
| quaternary carbon atom | An atom of carbon to which four other carbon atom's are attached. (05 Mar 2000) |
