Answer
Atoms
Explanation
## This question is foundational to chemistry and physics, asking about the essential building block of all matter.## Substances are made of atoms. Atoms combine in certain ways to create molecules or compounds, each being considered a substance in chemistry. A "molecule" is the smallest portion of a compound or element that maintains the properties of that compound or element. Despite being a critical component of a substance, considering that molecules are made up of atoms, it's accurate to conclude that all substances are made of atoms.## Additionally, each element has isotopes, which are atoms with differing numbers of neutrons. However, as indicated previously, even isotopes are composed of atoms. Therefore, even when considering isotopes, all substances are necessarily composed of atoms.
