Examine the false statement. In the Bohr model of an atom, an electron's path is not known exactly. Which answer choice rewords the false statement so it is true?

a. In the Bohr model of an atom, an electron's path follows a defined orbit inside the nucleus.

b. In the Bohr model of an atom, an electron's path follows a defined orbit around the nucleus.

c. In the Bohr model of an atom, an electron's path follows an erratic pattern inside the nucleus.

d. In the Bohr model of an atom, an electron's path follows an erratic pattern around the nucleus.

b. In the Bohr model of an atom, an electron's path follows a defined orbit around the nucleus.

Explanation:

Neil's Bohr was working with Ernest Rutherford on the theoretical aspects of atomic structure. He was highly impressed by Rutherford's new atomic model in which electrons revolved around the nucleus located at the centre. He could not understand the analogy between the Rutherford model and the movement of the planets around the sun, because the planets are electrically neutral while the electrons are heavily charged with negative electricity.

From the theory of electricity, we also known that revolving electric charge always emits electromagnetic waves. The emission of electromagnetic waves must result in the loss of energy by the emitting particle and this led the electrons in the Rutherford model spiral toward the central nucleus.

Bohr Model of an atom therefore postulate that;

an electron's path follows a defined orbit around the nucleus.

an electron did not radiate energy if stayed in one orbit.
