The term 'electron cloud' describes the Bohr model's location of electrons. True or False?

I believe the answer is true, but I would just prefer to be certain.

    Bohr model.....

    The original Bohr model (referring to hydrogen) had electrons in specific energy levels at specific distances from the nucleus. The term "electron cloud" came later, and refers to electrons having nonspecific locations within the atom.

    So no, the term "electron cloud" is not something that Bohr would have used, not early on, anyway. Only later, when Bohr was involved in quantum mechanics, would he have referred to an "electron cloud", and that was well after his original notions had been discarded.

    Some teachers make the mistake of teaching the Bohr model as if it had any involvement in current atomic theory. We should teach the Bohr model as a historical artifact, one which is important to the development of the modern atomic theory, but not as something which is part of modern atomic theory.

    The Bohr model describes electrons as a dot-point.

    The electron has a duality of character. It is a cloud of varying density. Because of this variation in density, there will be a 'centre of gravity/mass'. It is this 'centre of mass' that Bohr probably observed. .
