Respuesta :
The smallest unit that combines chemically or physically to form molecules and compounds is called an atom. They are composed of electrons and protons and neutrons in the nucleus.
The correct answer is:
Option d. To achieve a more stable electron configuration for both atoms.
This can be explained as:
- Atoms do not always bond to complete eight electrons in their shells.
- Atoms do not react to follow the octet rule.
- Electrons don't need to be filled in the shells of atoms of both the shells as some atoms lose electrons too.
Therefore to achieve stable configuration atoms bond with other atoms.
