what are the properties of ionic and covalent compounds
Ionic compounds:
1. Formed by the transfer of electrons from one atom to another.
2. Composed of oppositely charged ions held together by electrostatic forces of attraction.
3. Generally have high melting and boiling points.
4. Typically solid at room temperature.
5. Conduct electricity when dissolved in water or in molten state, but not in solid state.
6. Solubility in water varies widely.
7. Tend to form crystalline structures.
Covalent compounds:
1. Formed by the sharing of electrons between atoms.
2. Composed of molecules.
3. Generally have lower melting and boiling points compared to ionic compounds.
4. Exist in all three states of matter (solid, liquid, and gas) at room temperature.
5. Poor conductors of electricity in all states.
6. Solubility in water varies widely.
7. Tend to have lower densities compared to ionic compounds.
