“covalent bond”的概念、定义、翻译、参考文献-科学参考

covalent bond

Chemistry

See chemical bond.

Chemical Engineering

A type of chemical bond that involves the electrostatic attraction between a pair of atoms through the sharing of electrons and the positive nuclei. This bond was discovered by American chemist Gilbert Newton Lewis FRS (1875–1946).

Biology

A type of chemical bond in which atoms are held together in a molecule by sharing one or more pairs of electrons in their outer shells. For example, in the water molecule (H₂O) each hydrogen atom forms a covalent bond by sharing its only electron with one of the six electrons in the outer shell of the oxygen atom. Coordinate (or dative) bonds are covalent bonds in which one of the atoms supplies both the electrons. Single bonds are those in which one pair of electrons is shared; in double or triple bonds two or three pairs, respectively, are shared.

Geology and Earth Sciences

Bond in which a pair (or pairs) of electrons is shared between two atoms. The bond is often represented by drawing a single line between the symbols of the two atoms that have bonded together. Sometimes the bonding is between atoms of different elements (e.g. hydrogen chloride, H–Cl), and sometimes between atoms of the same element (e.g. fluorine, F–F). The name ‘molecule’ is used to describe any uncharged particle containing covalently bonded atoms. See also hydrogen bond; ionic bond; metallic bond.
