1. Ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of positively and negatively charged ions. Covalent bonds involve the sharing of electrons between atoms.
2. Ionic bonds typically form between a metal and a nonmetal, while covalent bonds typically form between two nonmetals.
3. Ionic bonds are typically stronger than covalent bonds.
4. Ionic compounds tend to have higher melting and boiling points compared to covalent compounds.
5. Ionic compounds tend to be more soluble in water compared to covalent compounds.
6. Ionic compounds tend to conduct electricity when dissolved in water or melted, while covalent compounds do not conduct electricity in any state.
7. Ionic bonds are formed through electrostatic attraction between oppositely charged ions, while covalent bonds are formed through the sharing of electrons.

Ionic Bonds
- Formation: Formed between atoms with significant differences in electronegativity (usually metals and nonmetals).
- Bond Type: Electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).
- Electron Transfer: One atom completely transfers electrons to another, resulting in the formation of ions.
- Strength: Typically strong and long-lasting due to the strong electrostatic forces.
- Solubility: Ionic compounds are usually soluble in polar solvents like water because water molecules can solvate the ions.
- Electrical Conductivity: In the liquid or molten state, ionic compounds conduct electricity due to the movement of ions.
- Melting and Boiling Points: Have high melting and boiling points due to the strong ionic interactions.
- Examples: Sodium chloride (NaCl), calcium oxide (CaO), potassium iodide (KI)
Covalent Bonds
- Formation: Formed between atoms with similar electronegativities (usually nonmetals).
- Bond Type: Sharing of electrons between atoms.
- Electron Sharing: Atoms contribute one or more electrons to form a shared pair that is attracted to both nuclei.
- Strength: Can vary in strength depending on the number of shared electrons and the size of the atoms involved.
- Solubility: Covalent compounds are generally less soluble in water than ionic compounds.
- Electrical Conductivity: Do not conduct electricity in the pure state.
- Melting and Boiling Points: Have lower melting and boiling points compared to ionic compounds due to weaker covalent interactions.
- Examples: Hydrogen (H2), methane (CH4), water (H2O)
