WebSubtract the number of e- from p+. Subtract the number of p+ from the mass number. Add the mass number to the number of e-. Question 35. 30 seconds. Report an issue. Q. This model was developed after J.J. Thompson discovered electrons, a particle smaller than an atom. Is shows electrons floating freely in a positive space. WebJun 22, 2014 · Chemistry Bohr Model of the Atom Excited States and Ground States Key Questions What is the ground state of an atom? The ground state describes the lowest possible energy that an atom can have. Atoms may occupy different energy states. The energy states are discrete, i.e. they occur at specific values only. happiest cities in united states

WebApr 8, 2024 · The possible orbits are known as energy levels. One of the weaknesses of Bohr's model was that he could not offer a reason why only certain energy levels or orbits were allowed. Figure 10.4. 1: The energy levels of the electrons can be viewed as rungs on a ladder. Note that the spacing between rungs gets smaller at higher energies (CC BY … http://physics.bu.edu/~duffy/sc546_notes04/bohr_model.html WebIn the Bohr model of the atom, for an electron that is in the orbit of lowest energy, its orbital angular momentum has magnitude equal to the reduced Planck constant, denoted ħ. The Bohr magneton is the magnitude of the magnetic dipole moment of an electron orbiting an atom with this angular momentum. chain link fence with razor wire details
