Match the particle to its' description:

Question

1. 42He
2. 0 -1 e
3. Y
4.
Is the same as a Helium atom
5.
Is an electron:
6.
Is pure energy:

a.Beta particle
b.Gamma particle
c.Alpha particle

Answer 1

Let's match the particles to their corresponding descriptions:

1. \( ^4_2He \) - This is a Helium nucleus, which consists of 2 protons and 2 neutrons.
   Match: 3. Is the same as a Helium atom
   Answer: c. Alpha particle (since an alpha particle is essentially a Helium nucleus.)

2. \( 0^{-1}e \) - This notation represents a beta particle, specifically an electron.
   Match: 5. Is an electron
   Answer: a. Beta particle

3. \( \gamma \) - This symbol represents a gamma ray, which is a form of electromagnetic radiation (pure energy).
   Match: 6. Is pure energy
   Answer: b. Gamma particle

So, the final matches are:

• 1 (42He) -> c. Alpha particle
• 2 (0 -1 e) -> a. Beta particle
• 3 (Y) -> b. Gamma particle
