Bond Order is the number of chemical bonds present between a pair of atoms is calculated using Bond Order=(1/2)*(Number of Bonding Electrons-Number of Antibonding Electrons). For example, for NO3-, you have three bonds: One double bond (2 electron pairs) and two single bonds (1 + 1= 2 electron pairs). When the nearest orbital shell is full, new electrons start to gather in the next orbital shell out from the nucleus, and continue until that shell is also full. Bond order: The number of chemical bonds present between two atoms of a molecule. Bond order indicates the stability of a bond. Covalent bonds are the most versatile, as they come in three kinds, depending on how many electron pairs are shared between bonding atoms. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. LibreTexts Chemistry: Bond Order and Length, LibreTexts Chemistry: Bond Lengths and Energies. Chemical bonds come in three basic types: Metallic bonds, which involve lots of "runaway" electrons not associated with particular parent atoms; ionic bonds, in which one atom donates an electron to another; and covalent bonds, in which the electron "orbitals" of bonding atoms overlap, resulting in sharing of electrons rather than offloading or gaining them outright. Ask your question. Bond order is an index of bond strength and is used extensively in valence bond theory. Best Trick to Calculate the Bond Order. To determine the bond order of a diatomic molecule such as H2, CO or HCl, you simply look at the kind of bond involved and that is your answer. Very frequently the reference bond distance is that of a single bond with n o =1.0. Divide the result by 2 to get the result. wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Bond-order usually predicted from the Molecular Orbital Theory 1,2. A molecule of oxygen gas (O2) has a double bond and a bond order of 2. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. Bond order = (Nb – Na) / 2. Most of the time, bond order is equal to the number of bonds between two atoms. However, if you’re familiar with the MO theory, you can compute the bond order by first filling the bonding and anti-bonding molecular orbitals with valence electrons according to the rules, and then refer to the expression. Bond order refers to the kind of bond in a molecule with two atoms.
