Question

alpha decay gamma decay beta decay neutron decay which type of decay involves the emission of an alpha particle? 3/10

Explanation:

Alpha decay is a type of radioactive decay where an atomic nucleus emits an alpha particle. This process reduces the atomic number of the nucleus by 2 and the mass number by 4. Gamma decay involves the emission of gamma rays (high - energy photons) to release excess energy from a nucleus without changing its atomic or mass number. Beta decay (including beta - minus and beta - plus) involves the transformation of a neutron into a proton (beta - minus) or a proton into a neutron (beta - plus) with the emission of an electron or positron respectively. Neutron decay is not a standard named decay type like the others in the context of common radioactive decay classifications.

Alpha decay
