Why do only valence electrons involve in bond formation ? Why not electron of inner shells ? Explain.
- When two atoms come sufficiently close together the valence electrons of each atom experience the attractive force of the nucleus in the other atom.
- The nucleus and the electrons in the inner shell remain unaffected when atoms come close together.
- The electrons in outermost shell of an atom get affected.
- Thus electrons in valence shell are responsible for the formation of bond between atoms.
