Molecule:
* Definition: A molecule is formed when two or more atoms bond together, regardless of the types of atoms involved.
* Examples:
* Diatomic molecules: Oxygen (O₂), Nitrogen (N₂)
* Polyatomic molecules: Water (H₂O), Carbon dioxide (CO₂)
* Giant molecules: Polymers like polyethylene
Compound:
* Definition: A compound is a type of molecule formed when two or more different atoms bond together.
* Key Point: All compounds are molecules, but not all molecules are compounds.
* Examples: Water (H₂O), Carbon dioxide (CO₂), Sodium chloride (NaCl)
Here's a simple analogy:
Think of a molecule as a house, and a compound as a specific type of house.
* A house can be made of various materials (atoms).
* A specific type of house, like a bungalow or a mansion, is built using different materials (different types of atoms).
In summary:
* Molecule: A group of atoms held together by bonds.
* Compound: A molecule composed of at least two different types of atoms.
