Answer:
The cause of the chemical bonding of atoms of an element is to attain stability as per the Octet rule or Duplet rule. If you look for examples of chemical bonds, you will see that all noble gases do not form any chemical bond. This is so because they have attained stability by completing their Octet or Duplet.
