According to Planck's quantum theory, what is the smallest unit of energy that can be emitted or absorbed by an atom?
Photon
Electron
Proton
Neutron
Answers (1)
Option A) Radiation energy could not emit or absorbs consistently but it could emit or absorbs in discrete quantities. These small bundles of energy are called quant a in terms of light these bundles are referred as photon.
Option B) One of the fundamental (and hardest to understand) principles of quantum mechanics is that the electron is both a particles and a wave.An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound).
Option C) A small, positively charged particle of matter found in the atoms of all elements. Streams of protons generated by special equipment can be used for radiation treatment. A proton is a stable subatomic particle..An elementary particle with a positive charge, is found in the nucleus of an atom. notes for proton. A proton is over a thousand times heavier than an electron.
Option D) Neutrons are subatomic particles that are one of the primary constituents of atomic nuclei. Neutrons do not have any net electric charge associated with them. They do, however, have a mass which is slightly greater in magnitude than that of a proton. Protons and neutrons are also called nucleons.
Therefore, the correct answer is A) Photon
