Given the information in the table:
- The mass of the particle is [tex]\( \frac{1}{2000} \)[/tex] atomic mass units (amu).
- The particle has a charge.
From these clues, a particle with a mass of [tex]\(\frac{1}{2000}\)[/tex] amu and a charge is indicative of an electron. The mass of a proton or a neutron is much closer to 1 amu. Additionally, protons are positively charged and neutrons are neutral, whereas electrons have a negative charge.
Electrons are also found outside of the nucleus, in contrast to protons and neutrons, which are located inside the nucleus.
Therefore, the best way to complete the table is:
[tex]\[
\begin{tabular}{|l|l|l|}
\hline Mass (amu) & Location & Charge \\
\hline $1 / 2,000$ & Outside of the nucleus & Has a charge \\
\hline
\end{tabular}
\][/tex]
This confirms that:
"Outside of the nucleus," because the particle is an electron.
is the correct explanation for how to complete the table.
