Webb26 aug. 2024 · Bohr’s model of the hydrogen atom also correctly predicts the spectra of some hydrogen-like ions. Hydrogen-like ions are atoms of elements with an atomic number Z larger than one ( Z = 1 for hydrogen) but with all electrons removed except one. For example, an electrically neutral helium atom has an atomic number Z = 2. WebbMain postulates of Bohr's model of an atom are: 1.
