  • a group of two or more atoms chemically bonded together
  • atoms that have gained or lost electrons and carry a charge
  • a substance made of two or more elements chemically bonded in a fixed ratio

Verified Answer :

Final answer:

In chemistry, isotopes are atoms of the same element with different neutrons, while compounds are substances made from two or more elements in fixed ratios. Molecules consist of two or more chemically bonded atoms, and ions are charged atoms that have gained or lost electrons.


Explanation:

Definitions of Terms in Chemistry

Let’s match each term to its respective definition:

  1. Isotope: Atoms of the same element with different numbers of neutrons. For example, Carbon-12 and Carbon-14 are both isotopes of carbon.
  2. Compound: A substance made of two or more elements chemically bonded in a fixed ratio. Water (H2O) is an example of a compound.
  3. Molecule: A group of two or more atoms chemically bonded together. An example of a molecule is O2, which is the molecular form of oxygen.
  4. Ion: Atoms that have gained or lost electrons and carry a charge. For instance, Na+ (sodium ion) is positively charged because it has lost an electron.
