- Can you tell me the difference between ionic and covalent bonds?
- Can you tell me some examples of ionic and covalent bonds?
- Examples of Ionic bonds: NaCl, MgOExamples of covalent bonds: H2, CH4
- Ionic bonds have melting and boiling point due to high electrostatic forces.Covalent bonds have low melting point as force of attraction is weak between the molecules.
- Why do ionic compounds have high melting point but covalent compounds have low melting point?
- Welcome
- Thanks for telling me. Now it will be easy for me to understand.
