Bond order.
It is defined as the number of covalent bonds in a molecule.Bond order is equal to one half of the difference between the number of electrons in the bonding (Nb) and anti-bonding (Na) molecular orbitals.
I.e Bond order =1/2 (Nb-Na)
angle of contact.
It is defined as the angle between the tangent to the liquid surface at the point of contact and solid surface inside the liquid is called as angle of contact The value of angle of contact depends upon (i) Nature of solid and liquid in contact (ii) Cleanliness of the surface in contact (iii) Medium above the free surface of liquid
