What are the similarities between the Rutherford-Bohr atom and the modern quantum mechanical model? What are the differences? Why is the Rutherford-Bohr model still useful? In what situations would you use one model over the other? Why?

Solutions

Expert Solution

Similarities: in both Bohr's model and Quantum mechanical model assign specific energies to electron and electrons are at different distances from the nucleus.

Differences: in Bohr's model, electrons are treated as particles & electrons are revolving aronud the nucleus in certain selected orbits, which are associated with a definite energy and hence it is one dimensional.

in Quantum mechanical model, electrons are mathematically treated as waves and hence it is three dimensional.
