Given the information provided, we know that the mass of the subatomic particle is 1 atomic mass unit (amu). Now, let’s go through the possible options and determine the correct statement based on this information.
### Step-by-Step Analysis:
1. Mass (amu): We are given that the mass of the particle is 1 amu. In atomic physics:
- A proton has a mass close to 1 amu.
- A neutron also has a mass close to 1 amu.
- An electron has a negligible mass of approximately 0 amu.
2. Possible Particles Given 1 amu Mass:
- The particle could be a proton or a neutron. An electron is ruled out because its mass is nearly 0 amu.
3. Location of the Particle:
- Protons and neutrons are located in the nucleus of an atom.
- Electrons are located in the electron cloud surrounding the nucleus.
4. Charge of the Particles:
- A proton carries a positive charge of +1.
- A neutron is electrically neutral, carrying a charge of 0.
- An electron carries a negative charge of -1.
### Evaluation of the Statements:
1. Its location is in the nucleus, because the particle is a proton or a neutron.
- This statement is correct. Given that both protons and neutrons have a mass of about 1 amu and are located in the nucleus.
2. Its location is in the nucleus, because the particle is a neutron or an electron.
- This statement is incorrect. While neutrons are in the nucleus, electrons are not; they are located in the electron cloud.
3. Its charge is +1, because the particle is a proton.
- This statement is partially correct. It’s true that a proton has a charge of +1. However, since the particle might also be a neutron, this statement alone doesn’t fully capture the possibilities.
4. Its charge is 0, because the particle is a neutron.
- This statement is partially correct. It’s true that a neutron has a charge of 0. However, since the particle might also be a proton, this statement alone doesn’t fully capture the possibilities.
### Conclusion:
Based on the provided information, the most accurate statement is:
Its location is in the nucleus, because the particle is a proton or a neutron. This statement correctly captures both potential cases given the mass of 1 amu.
