Which notation is commonly used to represent a beta particle in nuclear equations?

• A. eta^{+}
• B. ext{n}
• C. e^{-}
• D. ext{p}

Answer: (C)

Verified step by step guidance

1. Understand that a beta particle is an electron or positron emitted during radioactive decay, specifically beta decay.
2. Recall that beta minus decay involves the emission of an electron, which is represented as \(e^{-}\) or \(\beta^{-}\) in nuclear equations.
3. Note that the notation \(\beta^{+}\) represents a positron, which is the antiparticle of the electron and is emitted in beta plus decay.
4. Recognize that \(n\) stands for a neutron and \(p\) stands for a proton, which are different particles and not beta particles.
5. Therefore, the common notation for a beta particle (electron) in nuclear equations is \(e^{-}\) or \(\beta^{-}\).
