Let's analyze the characteristics provided in the partial table and match them to the correct subatomic particle.
1. Mass (amu): The mass of the particle is approximately [tex]\( \frac{1}{2000} \)[/tex] atomic mass units (amu).
2. Charge: The particle has a charge.
Given these points:
- We know that the mass of an electron is very small, approximately [tex]\( \frac{1}{2000} \)[/tex] the mass of a proton.
- Electrons also have a negative charge.
- Electrons are located outside the nucleus.
Now, let's review the options:
1. "Inside the nucleus," because the particle is a proton:
- Protons are inside the nucleus.
- However, the mass of a proton is 1 amu, not [tex]\( \frac{1}{2000} \)[/tex] amu, making this option incorrect.
2. "Inside the nucleus," because the particle is a neutron:
- Neutrons are inside the nucleus.
- Neutrons have no charge (neutral), and their mass is approximately 1 amu. Thus, this option does not match the charge and mass criteria.
3. "Outside of the nucleus," because the particle is a proton:
- Protons are inside the nucleus, not outside.
- Also, as mentioned, the mass of a proton is not [tex]\( \frac{1}{2000} \)[/tex] amu, so this option is incorrect.
4. "Outside of the nucleus," because the particle is an electron:
- Electrons are indeed located outside the nucleus.
- They have a very small mass, approximately [tex]\( \frac{1}{2000} \)[/tex] amu, which matches the given mass.
- Electrons also have a charge (negative charge), matching the charge mentioned in the table.
Therefore, based on the characteristics provided (mass of [tex]\( \frac{1}{2000} \)[/tex] amu and having a charge), the correct completion of the table is:
- Mass (amu): [tex]\( \frac{1}{2000} \)[/tex]
- Location: Outside of the nucleus
- Charge: Has a charge
Thus, the correct explanation is:
"Outside of the nucleus," because the particle is an electron.
