Questions asked by users might not always be phrased in the clearest way.
Ionic Bond:
- Formed between a metal (loses electron/s) and a non-metal (gains electron/s).
- Oppositely charged ions are attracted to each other by electrostatic attraction.
- Forms a crystalline solid, typically hard and brittle.
- High melting and boiling points due to strong electrostatic forces.
- Compounds are soluble in water.
- Conducts electricity when molten or dissolved in water.
Covalent Bond:
- Formed by sharing electron pairs between atoms.
- Non-metal elements form covalent bonds.
- Forms molecules, typically gases, liquids, or soft solids.
- Low melting and boiling points due to weaker forces.
- Generally insoluble in water.
- Does not conduct electricity.
