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.

\begin{tabular}{|l|l|l|}
\hline
Mass (amu) & Location & Charge \\
\hline
1 & & \\
\hline
\end{tabular}

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 :

Alright students, let's break down this problem step by step to understand the characteristics of the subatomic particle in question, based on the table given:

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

1. Interpreting the Mass:
- The particle has a mass of 1 atomic mass unit (amu).
- In atomic physics, the particles that typically have a mass close to [tex]\(1\)[/tex] amu are protons and neutrons.

2. Possible Candidates for the Particle:
- Proton: Has a mass of approximately [tex]\(1\)[/tex] amu, is located in the nucleus, and has a charge of [tex]\(+1\)[/tex].
- Neutron: Has a mass of approximately [tex]\(1\)[/tex] amu, is located in the nucleus, and has a charge of [tex]\(0\)[/tex].

3. Evaluating Each Given Statement:
Let's evaluate each statement based on our knowledge of protons and neutrons:

- Statement 1: "Its location is in the nucleus, because the particle is a proton or a neutron."
- Evaluation: Both protons and neutrons are located in the nucleus. Hence, this statement is correct.

- Statement 2: "Its location is in the nucleus, because the particle is a neutron or an electron."
- Evaluation: This is incorrect because electrons are not located in the nucleus; they are found in electron clouds surrounding the nucleus. Hence, this statement is incorrect.

- Statement 3: "Its charge is [tex]\(+1\)[/tex], because the particle is a proton."
- Evaluation: A proton indeed has a charge of [tex]\(+1\)[/tex]. Hence, this statement is correct.

- Statement 4: "Its charge is [tex]\(0\)[/tex], because the particle is a neutron."
- Evaluation: A neutron indeed has no charge. Hence, this statement is correct.

4. Conclusion:
Based on the given mass of [tex]\(1\)[/tex] amu and our understanding of subatomic particles:
- The correct statements are:
- "Its location is in the nucleus, because the particle is a proton or a neutron."
- "Its charge is [tex]\(+1\)[/tex], because the particle is a proton."
- "Its charge is [tex]\(0\)[/tex], because the particle is a neutron."

From this, we can conclude the following correct and complete answer:
- Its location is in the nucleus, because the particle is a proton or a neutron.
- Its charge is [tex]\(+1\)[/tex], because the particle is a proton.
- Its charge is [tex]\(0\)[/tex], because the particle is a neutron.

These detailed steps should guide you to understand the nature and characteristics of the subatomic particle in question.
