Frequently Asked Question

Q1: What is Bonding and what are its types?

A1: Physical state of existing in a bound form of two or more atoms together is called Bonding. Dissociation is the external energy required to get back the bonded atoms to free state as energy is needed to break the bonds. Type of bonding in solids are,

  • Primary bonds which include iconic, covalent and metallic bonding
  • Secondary bonds which have Vander waal’s and hydrogen bonds.
