Of the three types of radioactivity characterized by Rutherford,which are particles?
A)β-rays
B)α-rays, β-rays, and γ-rays
C)γ-rays
D)α-rays and γ-rays
E)α-rays and β-rays

Question

Quizplus · Accepted Answer

α-rays and β-rays are particles, while γ-rays are not particles but instead are a form of electromagnetic radiation. Therefore, only option D (α-rays and γ-rays) can be eliminated, leaving options A, B, and E. However, option B includes all three types of radioactivity, not just the particle types, so it can also be eliminated. This leaves option E (α-rays and β-rays) as the correct choice for the two types of radioactivity that are particles.
