Moreover, an atom contains a nucleus (made up of neutrons and protons) and electrons.
Answer:
The 'simple building blocks of matter' are known as atoms. The properties of the chemical element are the smallest constituent unit of substance. Molecules are made up of one or more atoms connected by covalent (chemical) bonds.
Explanation:
The term molecule is also used for any gaseous particle in the kinetic theory of gases, irrespective of its structure. Usually, atoms and complexes related by non-covalent interactions, such as bonds of hydrogen or ionic bonds, are not called independent molecules. It is normal to have molecules as elements of matter.
