To determine what a compound is composed of, let's analyze the options provided:

1. **Elements**: Compounds are made from two or more elements that are chemically combined in fixed ratios. While elements are part of compounds, they are not what compounds are solely composed of.

2. **Isotopes**: Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. While isotopes can appear in compounds, they are not a definitive composition of a compound.

3. **Atoms**: This is the correct answer. Compounds are formed when two or more different kinds of atoms (elements) bond together through chemical reactions. Therefore, the composition of a compound fundamentally involves these atoms.

4. **Molecules**: Compounds can exist as molecules, which are groups of atoms bonded together. However, saying that a compound is composed of molecules could be misleading as molecules can also consist solely of the same type of atom.

### Final Answer
A compound is composed of **Atoms**.
