Explanation / Answer

Answer 4.

An atom is a pure element i.e it has the actual and original physical and chemical properties of a single element, whereas a molecule is a uniform combination/compunding of two or more same or different elements.

An atom is made up of protons neutrons and electrons , while molecules are made up of atoms.

Original properties of element are always present in an atom while a molecule may or may not be similar o the physical and chemical properties of the parent atoms.

An atom does not contain a chemical bond while the atoms of a molecule are bounded by a chemical bond.

In nature molecules are more common than pure atoms.

Molecules are far more stable than single atoms.

eg. Water molecules cover almost 70-80% of earth, while hydrogen atom in its free form is highly unstable and can be seen in the interiors of the sun.
