Question

1. what is emitted during gamma emission?

helium nuclei
electromagnetic radiation
beta particles
electrons

Explanation:

Gamma emission is a type of radioactive decay. During gamma emission, an unstable nucleus releases energy in the form of electromagnetic radiation (gamma rays). Helium nuclei are emitted during alpha decay. Beta particles (which are high - speed electrons or positrons) are emitted during beta decay. Electrons (in the context of nuclear decay, beta particles are a more specific term for the emitted electrons in beta decay) are not the correct general term for what is emitted in gamma decay.

Answer:

electromagnetic radiation
