Question
Compare the relative masses of protons, neutrons, and electrons.
Answer
Protons and neutrons have approximately the same mass, which is about 1 atomic mass unit (amu), while electrons have a much smaller mass, approximately 1/1836 of a proton's mass. Therefore, protons and neutrons are considered to have significant mass compared to electrons.
Explanation
This question tests the student's understanding of the fundamental properties of subatomic particles, specifically their mass. It requires recall of the relative mass values and the ability to compare them, which is essential for understanding atomic structure.
Common mistake
Relative Mass Comparison Mistake
Students often confuse the relative masses of protons, neutrons, and electrons, thinking they are all similar.
Remember that protons and neutrons have a relative mass of approximately 1, while electrons have a much smaller relative mass of about 1/1836.
