(b)What is the cause of chemical bonding (or chemical combination) of atoms of elements?

Solution:

(a) Noble gases, also known as inert gases, are gases that do not react with other elements and belong to group 18. They are stable, non-reactive elements. Noble gases include helium, neon, argon, krypton, xenon, and radon. Except for helium, the electrical arrangement of noble gases will have 8 electrons in the outermost shell. As a result, they are the most reliable.

(a) To achieve stability, atoms form chemical bonds by acquiring an inert gas electron configuration by losing or gaining electrons.
