What is the fundamental force responsible for binding protons and neutrons together in the nucleus?

The strong nuclear force is the fundamental force that binds protons and neutrons (nucleons) together in the nucleus. It is a short-range force that overcomes the repulsive electromagnetic force between protons.

Which of the following particles is emitted during beta-minus decay?

Beta-minus decay involves the emission of an electron (beta particle) from a nucleus. This occurs when a neutron in the nucleus converts into a proton, releasing an electron and an antineutrino.

What is the term for the minimum amount of energy required to remove an electron from the outermost shell of an atom in its ground state?

Ionization energy is the energy required to completely remove an electron from an atom or ion in its ground state. It is a measure of the atom's ability to hold onto its electrons.

Which of the following transitions in the hydrogen atom results in the emission of the highest energy photon?

The energy of emitted photons in hydrogen atom transitions is highest when the electron falls from a higher energy level to a lower one. The transition from n = 4 to n = 5 corresponds to the highest energy difference among the options provided.
