What type of radiation is emitted during alpha decay?
Correct Answer: Alpha particles
- Step 1: Understand what alpha decay is. It is a type of radioactive decay.
- Step 2: Know that during alpha decay, the nucleus of an atom loses particles.
- Step 3: Identify the particles that are lost. In alpha decay, the particles lost are called alpha particles.
- Step 4: Recognize that an alpha particle is actually a helium nucleus, which consists of 2 protons and 2 neutrons.
- Step 5: Conclude that during alpha decay, helium nuclei (alpha particles) are emitted from the nucleus.
