Gamma Emission definitions Flashcards

A process where an excited atom emits a gamma ray, a high-energy photon, without changing its mass or atomic number.

A high-energy photon with no mass or charge, part of the electromagnetic spectrum, emitted during gamma emission.

A particle of light representing a quantum of electromagnetic energy, with no mass or charge.

The range of all types of electromagnetic radiation, including gamma rays, characterized by varying wavelengths and frequencies.

An isotope of thallium that can undergo gamma emission, remaining unchanged in mass and atomic number.

A condition where an atom's electrons occupy higher energy levels than the ground state, often preceding gamma emission.

A region around an atom's nucleus where electrons are likely to be found, changing during gamma emission.

The ability of radiation to ionize atoms, with gamma rays having low ionizing power compared to other particles.

The ability of radiation to pass through materials, with gamma rays having high penetrating power.

A type of radioactive decay where an atom emits an alpha particle, often occurring alongside gamma emission.

A radioactive decay process where a beta particle is emitted, frequently accompanying gamma emission.

A protective barrier made of lead, used to block the penetrating power of gamma rays.

A dense material used to protect against the high penetrating power of gamma rays.

The total number of protons and neutrons in an atom's nucleus, unchanged during gamma emission.

The number of protons in an atom's nucleus, remaining constant during gamma emission.
