Question

bonding having cohesive energy in the range 0.1 to 05 eV/atom.​

Answer 1

The strength of a bond is measured by the bond energy, which is the amount of energy necessary to break the bond. In general, molecular bonds have bond energies of 1 to 5 eV. Hydrogen bonds have bond energies in the range 0.1 to 0.5 eV, and van der Waals bonds have bond energies less than or equal to 0.1 eV.

The ionization energy of an atom is the energy required to remove an electron from that atom. The electron affinity of an atom is the energy released when an electron is added to that atom. These numbers are important for finding the bond energy of ionic bond
