Which of the following types of radiation results in the loss of an electron?
A
Emission of alpha particles
B
Emission of beta particles
C
Emission of gamma particles
Verified step by step guidance1
Understand the types of radiation: Alpha, beta, and gamma radiation are different types of radioactive decay processes.
Alpha particles consist of 2 protons and 2 neutrons, and their emission does not involve the loss of an electron.
Beta particles are high-energy, high-speed electrons or positrons emitted by certain types of radioactive nuclei. The emission of beta particles involves the transformation of a neutron into a proton, with the release of an electron (beta particle).
Gamma radiation involves the emission of high-energy photons and does not result in the loss of an electron.
Conclude that the emission of beta particles is the type of radiation that results in the loss of an electron, as it involves the release of an electron from the nucleus.
