All of the above. e. None of the above. chose the response which is MOST true regarding the subatomic particles. Select one: a. Protons have no charge. b. Neutrons have a charge. c. Electrons have no charge. d. All of the above e. None of the above
The Correct Answer and Explanation is:
First Question:
The correct answer is:
d. All of the above
Explanation:
- Protons have a mass of 1 AMU: This is correct. A proton’s mass is approximately 1 atomic mass unit (AMU), which is equivalent to around 1.672×10−271.672 \times 10^{-27}1.672×10−27 kg.
- Neutrons have a mass of 1 AMU: This is also correct. Neutrons, like protons, have a mass of about 1 AMU (1.675×10−271.675 \times 10^{-27}1.675×10−27 kg).
- Electrons do not have a mass of 1 AMU: This is true as well. The mass of an electron is much smaller than that of a proton or neutron. It is approximately 9.11×10−319.11 \times 10^{-31}9.11×10−31 kg, which is about 1/1836 the mass of a proton. Therefore, electrons have a negligible mass when compared to protons and neutrons.
Second Question:
The correct answer is:
e. None of the above
Explanation:
- Protons have no charge: This is false. Protons have a positive charge (+1).
- Neutrons have a charge: This is also false. Neutrons are electrically neutral, meaning they have no charge.
- Electrons have no charge: This is false as well. Electrons have a negative charge (-1).
