Final answer:
Covalent bonding is the type of bonding found in all molecular substances, where atoms share electrons to form molecules.
Step-by-step explanation:
The type of bonding found in all molecular substances is covalent bonding. In covalent bonding, atoms share electrons to achieve a full valence shell, which gives rise to individual molecules with distinct chemical properties. This is opposed to ionic bonding, where electrons are transferred between atoms, leading to the formation of positively and negatively charged ions, and metallic bonding, where electrons are free to move throughout the structure of metal atoms. While hydrogen bonding is a strong type of intermolecular force often seen in molecules containing hydrogen, it is not a primary chemical bond but rather an interaction that occurs between molecules that have covalent bonds. Hence, every molecular compound has covalent bonds holding the atoms together within a molecule.
Examples of everyday objects containing these bonds include:
- Covalent bonds: Water (H2O), sugar (C12H22O11)
- Ionic bonds: Table salt (NaCl), baking soda (NaHCO3)
- Metallic bonds: Copper wires (Cu), aluminum foil (Al)
