Answer
**Molecule**:
A molecule is a group of two or more atoms bonded together. These atoms can be of the same element or different elements. Molecules are the smallest units of a chemical compound that retain the chemical properties of that compound. They can exist as discrete entities or as part of a larger structure. Molecules can have a wide range of sizes and complexities, from simple diatomic molecules like oxygen gas (O2) to complex organic molecules like DNA or proteins. In a molecule, the atoms are held together by chemical bonds, which can be covalent (sharing of electrons) or ionic (attraction between oppositely charged ions).
**Compound**:
A compound is a substance composed of two or more different elements chemically bonded together in fixed proportions. Unlike mixtures, where substances are physically combined and can be separated by physical means (e.g., filtering or distillation), compounds are chemically combined, and their constituent elements are bonded together in specific ratios. Compounds have distinct chemical properties that differ from the properties of their constituent elements. Examples of compounds include water (H2O), table salt (NaCl), and glucose (C6H12O6). Compounds can be represented by chemical formulas that indicate the types and ratios of atoms present in the compound.
