Which statement accurately describes the relative strengths of the forces within an atom's structure?
Which statement accurately describes the relative strengths of the forces within an atom's structure?
- The gravitational force is the primary force that holds the nucleus together, overpowering the electrostatic force.
- The electrostatic force is significantly stronger than the strong nuclear force, causing the nucleus to destabilize over time.
- The strong nuclear force is stronger than the electrostatic force, holding the nucleus together despite the repulsion between protons. (correct)
- The electrostatic force and the strong nuclear force are equal in strength, maintaining the nucleus in a state of equilibrium.
If an electron absorbs a photon with enough energy, what might happen?
If an electron absorbs a photon with enough energy, what might happen?
- The atom will maintain its position, and the photons can not be abosrbed.
- The atom will become a negatively charged ion.
- The electron will fall into the nucleus.
- The electron may be ejected from the atom entirely. (correct)
