Bond Parameters

Many factors decide the covalent bonding between atoms. Some of the bond parameters are bond angle, bond order, enthalpy, bond length, etc. These parameters decide what kind of bond will form in atoms. Hence it is crucial to understand these parameters in detail and understand how changing these parameters affects the kind of bonding or various characteristics.

Bond Dissociation Energy

The tendency of an atom to attract an electron is known as its electronegativity.
