Students are completing a table about a particular subatomic particle that helps make up an atom. The students have filled in one cell of the table so far.

[tex]\[
\begin{tabular}{|l|l|l|}
\hline
Mass $( amu )$ & Location & Charge \\
\hline
1 & & \\
\hline
\end{tabular}
\][/tex]

Based on the information shown, which statement about the subatomic particle must be correct?

A. Its location is in the nucleus, because the particle is a proton or a neutron.
B. Its location is in the nucleus, because the particle is a neutron or an electron.
C. Its charge is +1, because the particle is a proton.
D. Its charge is 0, because the particle is a neutron.



Answer :

Let's analyze the information given about the subatomic particle in the context of what we know about the structure of an atom and the characteristics of its particles.

1. Mass [tex]\(1 \text{ amu}\)[/tex]:
- The mass [tex]\(1 \text{ amu}\)[/tex] is characteristic of either a proton or a neutron. Electrons have a much smaller mass (approximately [tex]\(0.000548 \text{ amu}\)[/tex]) that is often approximated to 0. Therefore, we can rule out electrons.

2. Location (Not specified yet):
- Since we have identified that the particle is either a proton or a neutron, we know that these particles reside in the nucleus of an atom. Thus, its location must be the nucleus.

3. Charge (Not specified yet):
- Protons have a charge of [tex]\(+1\)[/tex].
- Neutrons have a charge of [tex]\(0\)[/tex].

Given these points, let's look at the statements one by one:

- Statement: "Its location is in the nucleus, because the particle is a proton or a neutron."
- This statement is correct. Both protons and neutrons are located in the nucleus of an atom.

- Statement: "Its location is in the nucleus, because the particle is a neutron or an electron."
- This statement is incorrect. Electrons are not located in the nucleus; they orbit around the nucleus.

- Statement: "Its charge is [tex]\(+1\)[/tex], because the particle is a proton."
- While this statement could theoretically be true under other circumstances, it is not necessarily correct for this specific question, as the particle in question could also be a neutron, which has no charge.

- Statement: "Its charge is [tex]\(0\)[/tex], because the particle is a neutron."
- This statement is correct. If the particle in question is a neutron, it will indeed have no charge.

Given that multiple choice questions often have more than one technically correct option but ask for the best response based on given information, the two most accurate statements given the specified mass (1 amu) are the first and the last:

1. Its location is in the nucleus, because the particle is a proton or a neutron.
2. Its charge is [tex]\(0\)[/tex], because the particle is a neutron.

Thus, both of these statements are correct based on the provided information.
