प्रश्न
Why covalent compounds are different from ionic compounds?
उत्तर
Ionic compounds, on the other hand, are the compounds that are formed by the complete transfer of valence electrons between the constituent atoms. For example, a molecule of sodium chloride (NaCl) is formed when the sodium atom donates its one valence electron to the chlorine atom.
