Quick Answer: What nuclear emission has the greatest penetrating power?

Which nuclear emission has no charge and no mass?

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.

What is the penetrating power?

“Penetrating power” is defined as the power (length) of an electron beam transmitted for a substance. … In the case of a TEM, electrons that do not pass through the objective aperture are regarded to be absorbed. Thus, elastic scattering at high angles is regarded as absorption.

Which emission is the most charged?

Alpha particles are the largest of the emitted particles and are positively charged. They are composed of two protons and two neutrons that are bonded together, which is the same as a helium-4 nucleus. This makes them the most massive of the types of radioactive emission.

Which particle has the least mass?

The fundamental particle that has least mass is electron.
