An 'atom' is a 'nucleus' surrounded by an 'electron_cloud', i.e. a quantum system made of one or more bounded electrons. A standalone atom has direct part one 'nucleus' and one 'electron_cloud'. An O 'atom' within an O₂ 'molecule' is an 'e-bonded_atom'. In this material branch, H atom is a particular case, with respect to higher atomic number atoms, since as soon as it shares its electron it has no nucleus entangled electron cloud. We cannot say that H₂ molecule has direct part two H atoms, but has direct part two H nucleus.
