WebbA hydrogen-like atom (described by the Bohr model) is observed to emit six wavelengths, originating from all possible transitions between a group of levels. These levels have energies between − 0. 8 5 e V and − 0. 5 4 4 e V (including both these values). (a) Find the atomic number of the atom.

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. the pottery house frank lloyd wright
