Complete the following two statements regarding quantum-mechanical concepts associated with the Bohr model of the atom and refinements that resulted from the wave- mechanical atomic model. Two important quantum-mechanical concepts associated with the Bohr model of the atom are that eledtrons are particles moving in electron energy is quantized into
(b) Two important refinements resulting from the wave-mechanical atomic model are that the electron position is described in terms of a electron energy is quantized into both shells and subshells--each electron is characterized by , and , and quantum numbers.
