Answer 1

Answer:

Two important quantum-mechanical concepts associated with the Bohr model of the atom are (1) that electrons are particles moving in discrete orbitals, and (2) electron energy is quantized into shells. (b) Two important refinements resulting from the wave-mechanical atomic model are (1) that electron position is described in terms of a probability distribution, and (2) electron energy is quantized into both shells and subshells--each electron is characterized by four quantum numbers.

Explanation:

Answer 2

Part A:

The two important quantum-mechanical concepts associated with the Bohr model of the atom are:

(1) Electrons are particles moving in discrete orbitals.

(2) Electron energy is quantized into shells.

Part B:

The two important refinements resulting from the wave-mechanical atomic model are:

1. That electron position is described in terms of a probability distribution.
2. The electron energy is quantized into both shells and subshells each electron is characterized by four quantum numbers.
