Transcript text: The symbol ${ }_{-1}^{0} e$ is a symbol used for a(n) proton. alpha particle. neutron. beta particle. gamma ray.

Solution

Solution Steps

Step 1: Understand the Symbol

The symbol ${ }_{-1}^{0} e$ is used in nuclear physics to represent a specific type of particle. The notation ${ }_{Z}^{A} X$ is a common way to denote particles, where $Z$ is the atomic number (number of protons), $A$ is the mass number (number of protons and neutrons), and $X$ is the chemical symbol.

Step 2: Analyze the Given Symbol

In the symbol ${ }_{-1}^{0} e$:

The subscript $-1$ indicates the particle has a charge of $-1$.
The superscript $0$ indicates the particle has a mass number of 0.

Step 3: Identify the Particle

A particle with a charge of $-1$ and a mass number of 0 is characteristic of a beta particle. Specifically, this is a beta-minus particle, which is an electron emitted during beta decay.
