प्रश्न
Explain the following:
Atoms combine by transfer and sharing of an electron(s).
उत्तर
Atoms combine because they have incomplete valence shells and tend to attain a stable electronic configuration. So, to attain a stable electronic configuration, atoms of elements gain or share their electrons with other atoms.
