Answer:
One molecule is made of two or more atoms bonded together.
Step-by-step explanation:
Molecule is a substance which is made up chemically by two or more same or different atoms. The atoms joint together in a molecule due to a chemical bond. This chemical bond is formed either by mutual sharing of electrons or transfer of electrons between two atoms.
Examples:
A molecule of H₂O (water) is made up of two atoms of Hydrogen and one atom of Oxygen (H-O-H).
A molecule of CO₂ (Carbon Dioxide) is formed when a carbon atom is bonded to two oxygen atoms via a double bonds (O=C=O).
A molecule of N₂ (Nitrogen Gas) is formed between two nitrogen atoms through a triple bond (N≡N).
