Question

All of the following statements are true about Bohr's model of the atom except which one of the following?

• A. An electron may assume an infinite number of velocities
• B. An atom is most stable when its electronic configuration is that of the ground state
• C. The electron shell numbers represents the principal energy levels
• D. Electrons in orbitals closest to the nucleus have the lowest energy
• E. They are all consistent

Answer 1

The correct option is A An electron may assume an infinite number of velocities

A: An electron can not assume an infinite number of velocities, as each electron has fixed velocity , in each energy level.
The electrons in free atoms can will be found in only certain discrete energy states. These sharp energy states are associated with the orbits or shells of electrons in an atom, e.g., a hydrogen atom. One of the implications of these quantized energy states is that only certain photon energies are allowed when electrons jump down from higher levels to lower levels, producing the hydrogen spectrum. The Bohr model successfully predicted the energies for the hydrogen atom, but had significant failures that were corrected by solving the Schrodinger equation for the hydrogen atom.
