What is the main difference between alpha and beta radiation?
Correct Answer: Alpha particles have greater mass than beta particles.
- Step 1: Understand that alpha radiation consists of alpha particles.
- Step 2: Know that alpha particles are made up of 2 protons and 2 neutrons, which means they have a larger mass.
- Step 3: Learn that beta radiation consists of beta particles, which are either electrons or positrons.
- Step 4: Recognize that beta particles are much lighter than alpha particles because they are just single electrons or positrons.
- Step 5: Conclude that the main difference is that alpha particles are heavier (greater mass) than beta particles.
