The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
The correct answer is C<\/strong>.<\/p>\n\n\n\n
Explanation<\/h3>\n\n\n\n
To determine which diagram best represents the relationship between the masses of subatomic particles, we must compare the known masses of the proton, neutron, and electron.<\/p>\n\n\n\n
Relative Masses of Subatomic Particles:<\/strong><\/p>\n\n\n\n
    \n
  • Proton (p\u207a):<\/strong>\u00a0A proton has a relative mass of approximately 1 atomic mass unit (amu). Its actual mass is about 1.6726 x 10\u207b\u00b2\u2077 kg.<\/li>\n\n\n\n
  • Neutron (n\u2070):<\/strong>\u00a0A neutron also has a relative mass of approximately 1 amu. Its actual mass is about 1.6749 x 10\u207b\u00b2\u2077 kg.<\/li>\n\n\n\n
  • Electron (e\u207b):<\/strong>\u00a0An electron has a much smaller mass, approximately 1\/1836th of a proton’s mass. Its actual mass is about 9.109 x 10\u207b\u00b3\u00b9 kg.<\/li>\n<\/ul>\n\n\n\n
    Analyzing the Diagrams:<\/strong><\/p>\n\n\n\n
    The diagrams use a balance scale to visually compare the masses of two particles. The side of the scale that is lower holds the particle with the greater mass.<\/p>\n\n\n\n
      \n
    • Diagram A:<\/strong>\u00a0This diagram shows a proton and an electron in balance, suggesting they have equal mass. This is incorrect. A proton is vastly more massive than an electron.<\/li>\n\n\n\n
    • Diagram B:<\/strong>\u00a0This diagram shows the proton’s side is lower than the electron’s side, indicating that a proton is more massive than an electron. This statement is correct.<\/li>\n\n\n\n
    • Diagram D:<\/strong>\u00a0This diagram shows the neutron’s side is lower than the electron’s side, indicating that a neutron is more massive than an electron. This statement is also correct.<\/li>\n\n\n\n
    • Diagram C:<\/strong>\u00a0This diagram shows the neutron’s side is lower than the proton’s side. This indicates that a neutron is more massive than a proton. Comparing their precise masses (1.6749 x 10\u207b\u00b2\u2077 kg for a neutron vs. 1.6726 x 10\u207b\u00b2\u2077 kg for a proton), we see that the neutron is indeed slightly heavier. This statement is correct.<\/li>\n<\/ul>\n\n\n\n
      Why C is the Best Representation:<\/strong><\/p>\n\n\n\n
      While diagrams B, C, and D all depict factually correct relationships, the question asks for the best<\/em> representation. In chemistry and physics, the masses of the proton and neutron are often approximated as being equal (1 amu) because their masses are very close. However, they are not identical.<\/p>\n\n\n\n
      Diagram C illustrates the subtle but important difference in mass between a neutron and a proton. Choosing this option demonstrates a more precise understanding of particle physics than simply knowing that protons and neutrons are much heavier than electrons (as shown in B and D). The fact that a neutron is slightly heavier than a proton is a key detail that distinguishes them. Therefore, diagram C provides the most nuanced and specific correct relationship among the choices presented.<\/p>\n\n\n\n
