Question 12

Three statements about alpha (α\alphaα) particles and beta (β\betaβ) particles are listed:

  1. The magnitude of the charge on an α\alphaα-particle is twice the charge on a β\betaβ-particle.
  2. The mass of an α\alphaα-particle is much greater than the mass of a β\betaβ-particle.
  3. The average speed of an α\alphaα-particle on emission is greater than that of a β\betaβ-particle.

Which statements help to explain why α\alphaα-particles have a much shorter range in air than β\betaβ-particles?
