Strength of Bonds?

[Daniel Chang 3I]

Why are ionic bonds stronger than covalent bonds? And why does polarity matter in terms of strength for covalent bonds?

[Charles Gu 1D]

Ionic bonds have oppositely charged ions that create a coulombic attraction while covalent bonds only share electrons

To answer your second question, no covalent bond is 100% covalent -- they all have some ionic character. Thus the determining factors of ionic bond strength all apply to covalent bonds as well, including electronegativity and thus polarizing power.

Covalent bonds share electrons

[Sang Hyoun Hong 3G]

All bonds have ionic character. The strength of the bond is determined by the electronegativies of the atoms in the bond.

[Elizabeth Kim 4E]

Ionic bonds are stronger due to their particular ionic character. And polarization power depends in covalent bonds.
