Question

Why isn't it as easy to stop a beta particle?

a) Beta particles are very large
b) Beta particles have a positive charge
c) Beta particles are highly energetic and fast-moving
d) Beta particles have a neutral charge

Answer 1

Beta particles are not easy to stop because they are highly energetic and fast-moving, and have a smaller charge compared to alpha particles. They require thin sheets of metal for shielding and have much greater penetration power.

Step-by-step explanation:

Beta particles, which are fast-moving electrons, are not easy to stop because they are highly energetic and fast-moving. Beta particles are not easy to stop because they are highly energetic and fast-moving, and have a smaller charge compared to alpha particles. They require thin sheets of metal for shielding and have much greater penetration power.

Unlike alpha particles, which have a greater charge and are easily absorbed by air or a thin sheet of paper, beta particles have a smaller charge and require thin sheets of metal for shielding. They have much greater penetration power than alpha particles.
