WebThe Bohr model is a relatively primitive model of the hydrogen atom, compared to the valence shell model. As a theory, it can be derived as a first-order approximation of the hydrogen atom using the broader and much more accurate quantum mechanics and thus may be considered to be an obsolete scientific theory . WebJul 29, 2024 · Quick answer: The Bohr Model for Beryllium (Be) has 4 protons in the nucleus due to the atomic number of Be being 4. The Mass number is 9 which means Beryllium needs 5 neutrons in the nucleus. (Mass number = protons + neutrons, 9 = 4 + n). Beryllium has four electrons to balance the four protons.
