Question
Define the bond length.
✓
Answer
Bond length is defined as the equilibrium distance between the nuclei of two bonded atoms in a molecule.Bond lengths are expressed in terms of Angstrom ( $10^{-10} \mathrm{~m}$ ) or picometer ( $10^{-12} \mathrm{~m}$ ) and are measured by spectroscopic Xray diffractions and electron-diffraction techniques.
In an ionic compound, the bond length is the sum of the ionic radii of the constituting atoms ( $d=r_{+}+r_{-}$). In a covalent compound, it is the sum of their covalent radii $\left(d=r_A+r_B\right)$.
