Beta particles are:

Beta particles are:

• A. having weight and mass
• B. ionizing radiation like X rays
• C. deadly radiation
• D. large particles that easily pass through protective gear

Answer: (B)

Beta particles are high-energy electrons emitted by unstable nuclei. They are a form of ionizing radiation, meaning they have enough energy to knock electrons off atoms in matter. This ionizing capability is the defining feature that beta particles share with X rays, which is why the statement describing them as ionizing radiation like X rays is the best fit. It's worth noting that beta particles do have mass (they are electrons), but the important distinction in this context is their ionizing nature rather than their mass. They are not inherently “deadly” by themselves—their danger depends on exposure and shielding. They’re also not “large” particles; they’re relatively light and can be stopped by thin shielding like plastic or a few millimeters of metal, so they don’t pass easily through protective gear.
