Answer» Abond angleis theanglebetween two bondsoriginating from the same atom in a covalent species. eg. 1: eg. 2: Geometrically, abond angleis an anglebetween two converging lines. Bond order is the number of chemical bonds between a pair of atoms. For example, in diatomic nitrogen N≡N the bond order is 3, in acetylene H−C≡C−H the bond order between the two carbon atoms is also 3, and the C−H bond order is 1. Bond order gives an indication of the stability of a bond. The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is usually measured either in picometres or angstroms, with 1 Å = 100 pm. In principle, the sum of the two co equal the covalent bond length between two atoms, R = r + r. |
