Which is stronger between ionic and covalent bonds?

Answer 1

Generally speaking, covalent bonds are a stronger.

Remember, in covalent bonds a valence electron is shared between two atoms. In an ionic bond, one atom gives and electron to another atom. It takes less energy to break apart the positively charged atom from the negatively charged atom than it does to separate two atoms which are sharing an electron.

This is not always the case, however. There are a few ionic bonds that are stronger than covalent bonds. This is especially true when the ionic bonds form into a crystalline structure. There are a lot of them so it is harder to break them apart. It is also much harder to break an ionic bond in a vacuum, since there is nothing to lessen the electrostatic (Coulombic) interaction.

Generally, though, you can say that covalent bonds are stronger.

Answer 2

Ionic bonds are typically stronger than covalent bonds because they involve the transfer of electrons between atoms, leading to strong electrostatic attractions. Covalent bonds involve the sharing of electrons, which creates a weaker bond compared to the strong attraction in ionic bonds.
