To determine how to complete the table, let's analyze the information given:
1. Mass (amu): The subatomic particle has a mass of \( \frac{1}{2000} \, \text{amu} \).
2. Charge: The particle has a charge (although the sign is not specified in the table).
We need to match these characteristics to one of the known subatomic particles—protons, neutrons, and electrons.
### Step-by-Step Analysis:
Step 1: Identifying the Particle by Mass
- Proton: A proton has a mass of approximately \( 1 \, \text{amu} \).
- Neutron: A neutron also has a mass close to \( 1 \, \text{amu} \).
- Electron: An electron has a much smaller mass, approximately \( \frac{1}{2000} \, \text{amu} \).
Given that our particle has a mass of \( \frac{1}{2000} \, \text{amu} \), it matches the mass of an electron.
Step 2: Identifying the Location
To confirm our identification, let’s consider the location:
- Protons and Neutrons: Both protons and neutrons are located inside the nucleus.
- Electrons: Electrons are located outside the nucleus.
Since the particle in question has a mass of \( \frac{1}{2000} \, \text{amu} \) and electrons are the subatomic particles with this characteristic mass, we conclude that:
Final Decision:
- The particle is an electron.
- Electrons are located outside of the nucleus.
Therefore, the table should be completed as:
- Location: "Outside of the nucleus"
- Reason: "because the particle is an electron"
So, to summarize for the table completion:
\begin{tabular}{|l|l|l|}
\hline
Mass (amu) & Location & Charge \\
\hline
[tex]$1 / 2,000$[/tex] & Outside of the nucleus & Has a charge \\
\hline
\end{tabular}
The best explanation among the given options is:
- "Outside of the nucleus," because the particle is an electron
