Decreasing order of bond length:
Sio32 > [CO3] > Co2
What is bond length?
The equilibrium separation between the nuclei of two bound atoms in a molecule is referred to as the bond length.
The length of the bond increases with increasing atom size.
Bond multiplicity causes a decrease in bond length.
Rotational spectroscopy, X-ray diffraction, and other methods are used to measure it.
The length of the bond depends on how many electrons are bonded (the bond order). The higher the bond order, the stronger the attraction between the two atoms and the shorter the bond length. The length of the bond between two atoms is typically approximately equal to the sum of their covalent radii.
