Question

What types of bonds are strongest?

Answer 1

• Chemical bonds are formed by the transferring of electrons in terms of loss or gain or by the complete sharing of electrons.
• The strongest bond is the covalent bond that is formed by the sharing of electrons.
• The outer shell or valence shell electrons take part in the bond formation.
• Every atom, element, or compound wants to become stable by completing the valence shell of electrons either by loss or gain of electrons.
• Thus, covalent bonds are formed by equal sharing of electrons in atoms or groups of atoms.
• The bonding can occur in similar types of molecules or different types of molecules as well.
• Example: Hydrogen molecule ${\mathrm{H}}_2$, methane $\left({\mathrm{CH}}_4\right)$ , etc.
• The general sharing of electrons of an atom occurs as depicted in the picture.
  

Therefore, covalent bonds are strongest.
