Which of the following represents a beta particle?A.0−1e−1​ 0 ​ eB.24He24​ HeC.𝛼αD.𝛾γ

Break Down the Problem

1. Identify the particle representations given in the options.
2. Understand which representation corresponds specifically to a beta particle.

Relevant Concepts

• A beta particle is a type of subatomic particle that is typically represented as an electron or positron.
• Standard representations of particles:
  • Beta particle (electron): $^0_{-1} e$
  • Alpha particle: $^4_2 \alpha$ or $^4_2 He$
  • Gamma ray: $\gamma$

Analysis and Detail

1. Option A: $^0_{-1} e$ represents a beta particle (specifically, an electron).
2. Option B: $^4_2 He$ represents an alpha particle.
3. Option C: $\alpha$ represents an alpha particle, which is not a beta particle.
4. Option D: $\gamma$ represents a gamma ray, not a beta particle.

Verify and Summarize

The correct representation of a beta particle is clearly only found in option A. The other options either represent different particles (alpha ray and gamma ray).

Final Answer

A. $^0_{-1} e$ represents a beta particle.
