Students are completing a table about a particular subatomic particle that helps make up an atom.

\begin{tabular}{|l|l|l|}
\hline
Mass (amu) & Location & Charge \\
\hline
[tex]$1 / 2,000$[/tex] & & Has a charge \\
\hline
\end{tabular}

How should they complete the table?

A. "Inside the nucleus," because the particle is a proton.
B. "Inside the nucleus," because the particle is a neutron.
C. "Outside of the nucleus," because the particle is a proton.
D. "Outside of the nucleus," because the particle is an electron.



Answer :

To determine how to complete the table about the subatomic particle with the given information, let’s carefully analyze each piece of data provided:

1. Mass (amu): The particle has a mass of [tex]\( \frac{1}{2,000} \)[/tex] atomic mass units (amu).
2. Charge: The particle "has a charge."

Based on this information, we can classify the particle by the following characteristics:

- Mass:
- Protons and neutrons both have masses close to 1 amu.
- Electrons have a significantly smaller mass, approximately [tex]\( \frac{1}{2,000} \)[/tex] amu.

Given that the mass of the particle in question is [tex]\( \frac{1}{2,000} \)[/tex] amu, we can rule out protons and neutrons because their masses are close to 1 amu. This specific mass indicates that the particle is an electron.

- Charge:
- Protons have a positive charge.
- Neutrons have no charge.
- Electrons have a negative charge.

Given that the particle "has a charge," it further confirms that it must be an electron, as neutrons have no charge. The charge information does not directly help with distinguishing between a proton and an electron here, but we already know from the mass that the particle cannot be a proton.

- Location:
- Electrons are located outside the nucleus.
- Protons and neutrons are located inside the nucleus.

Since we have identified the particle as an electron based on its mass and charge, we now look at the location of electrons in an atom. Electrons are found outside the nucleus.

Therefore, the best way to complete the table is:

- Mass: [tex]\( \frac{1}{2,000} \)[/tex] amu
- Location: Outside of the nucleus
- Charge: Electron

So, the correct way to complete the statement is:
"Outside of the nucleus," because the particle is an electron.
