Verified step by step guidance1
Understand that a beta particle is an electron or positron emitted during radioactive decay, specifically beta decay.
Recall that beta minus decay involves the emission of an electron, which is represented as \(e^{-}\) or \(\beta^{-}\) in nuclear equations.
Note that the notation \(\beta^{+}\) represents a positron, which is the antiparticle of the electron and is emitted in beta plus decay.
Recognize that \(n\) stands for a neutron and \(p\) stands for a proton, which are different particles and not beta particles.
Therefore, the common notation for a beta particle (electron) in nuclear equations is \(e^{-}\) or \(\beta^{-}\).
