Common scientific expressions are 'ein Atom spalten' (to split an atom), 'der Kern eines Atoms' (the nucleus of an atom), or the description that something 'aus Atomen besteht' (consists of atoms).

molecule
An Atom is the smallest chemically indivisible building block of an element. A Molekül, by contrast, consists of at least two chemically bonded atoms. When a single building block of an element is meant, Atom is the right word; for a bonded unit made up of several atoms, Molekül is the right word.
Ein einzelnes Atom Sauerstoff gehört zum Element Sauerstoff.
A single oxygen atom belongs to the element oxygen.
Ein Molekül Sauerstoff besteht aus zwei gebundenen Sauerstoffatomen.
An oxygen molecule consists of two bonded oxygen atoms.
