Question

According to Bohr's planetary model of the atom, why don't the electrons collapse into the nucleus of the atom?

A. The neutrons repel the electrons, keeping them in their energy levels.
B. The electrons are moving so fast that the pull from the nucleus is not enough to attract them.
C. The positively charged protons repel the negatively charged electrons, keeping them in their energy levels.
D. The electrons spin onto the nucleus, but they bounce back out into energy levels.

Answer 1

According to Bohr's planetary model, electrons do not collapse into the nucleus due to the centrifugal force generated by their constant motion counteracting the electrostatic force of attraction between the protons and electrons.

Step-by-step explanation:

The electrons in an atom do not collapse into the nucleus due to the electrostatic force of attraction between the positively charged protons in the nucleus and the negatively charged electrons. According to Bohr's planetary model, the electrons occupy specific energy levels or orbits around the nucleus. These orbits are stable and do not collapse because the electrons are in a state of constant motion, moving very fast. The centrifugal force created by the electron's motion counteracts the electrostatic force of attraction, keeping the electrons in their orbits.
