Why con beta particles pass through materials more easily than alpha particles?

Question

Beta particles are not charged
Beta porticles move more slowy
Beta particles are smaller
Beta particles are made of pure energy

Answer 1

Beta particles are not charged, so they do not interact strongly with matter compared to alpha particles which carry a positive charge. As a result, beta particles can penetrate materials more easily. Additionally, beta particles are smaller and lighter compared to alpha particles, which allows them to travel at higher speeds and possess greater penetrating capability.
