You. why was niels bohr’s atomic model superior to all the earlier models? a. it proved that the atom was indivisible and therefore the smallest unit of matter. b. it showed how the electron could orbit the nucleus without falling into it. c. it was the first to show that the atom had no net charge. d. it used wave behavior to explain the positions of electrons around the nucleus.

B. It showed how the electron could orbit the nucleus without falling into it.

Explanation: -

Niels Bohr’s atomic model had the following main postulates:-

1. The electrons revolved around the nucleus at a fixed distance in fixed orbits.

2. As long as the electrons revolved around these orbits, they neither gained nor they lost energy.

3. Electrons jumped from one orbit to another only when certain discrete amount of energy is supplied or lost.

Thus the atom will be completely stable n the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.

Thus Niels Bohr’s atomic model superior to all the earlier models since it showed how the electron could orbit the nucleus without falling into it.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
