A coordinate covalent bond is a pair of electrons shared between two atoms which originated on one of the atoms;a covalent bond is a shared pair of electrons. Once formed, there is no difference between them. In an ammonium ion there are four covalent bonds,one of which is a coordinate ...

What is the difference between an ionic bond and a covalent bond?相关知识点: 试题来源: 解析 An ionic bond is formed when electrons are transferred from one aton to another to form negative and positive ions.A colvalent bond is formed when electrons are shared between two atoms....
A single covalent bond between two atoms generally allows the rotation of one part of a molecule relative to the other around the bond axis. A double bond prevents such rotation, producing a more rigid and less flexible arrangement of atoms. 相关知识点: 试题来源: 解析 正确 反馈 收藏 ...
The definition of a covalent bond is a chemical link between two atoms or ions in which the electron pairs are shared.
