Question

64. Bohr 's orbits are called stationary states because
a) electrons in them are stationary
b) their orbits have fixed radii
c) the electrons in them have fixed energy
d) the protons remain in the nuclei and are stationary​

Answer 1

Answer:

option c)

Explanation:

The model states that electrons in atoms move in circular orbits around a central nucleus ... it would mean an orbit of decreasing radius and approaching the nucleus in a spiral trajectory.

Answer 2

Answer:

C

Explanation:

Bcoz According to Bohr, electrons possess specific amount of energy as they move in circular orbits around nucleus.

If they lose their energy, then they will fall into the nucleus and the atom will be unstable.

So, option C is correct.
