(A) the total energy of an electron revolving in any stationary orbit is negative.
(R) energy can have positive or negative values.

A

if both assertion and reason are true and reason is the correct explanation of assertion.

B

if both assertion and reason are true but reason is not the correct explanation of assertion.

C

if assertion is true but reason is false.

D

if both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
Energy can have positive or negative values. in the atom. the electrons are bound . The negative energy of the revolving electrons does not allow the electrons to leave the atom. That the electrons are bound within the atom is indicated by energy being negative.
