Ionic vs Covalent bonds

• Cations have positive charges, while anions have negative charges.
• Ions are charged particles that result from the loss or gain of electrons.
• Ions are formed when atoms gain or lose electrons to achieve a full outer shell.
• In ionic compounds, metals always form cations and nonmetals always form anions.
• What is a covalent bond ?

  Sharing a pair of electrons.
• What is ionic bond ? the bond formed by the complete transfer of valence electron to gain stability.
• Ionic bond vs Covalent bond ?

  Covalent bonding involves the sharing of electrons between two or more atoms.

  Ionic bonds form when two or more ions come together and are held together by charge differences.
