प्रश्न

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

Advertisements

उत्तर

The atoms of elements undergo chemical bonding (or chemical combination) to attain the noble gas electronic configuration and become more stable. By chemical bonding, atoms share or transfer their electrons to make their outermost shells completely filled and thus attain stability.
