Which of the following is the most correct in regards to the mass spectrometer analysis of an element?
A) A mass spectrometer provides evidence of the existence of the proton.
B) A mass spectrometer provides evidence of the existence of the electron.
C) A mass spectrometer provides evidence for the existence of different isotopes.
D) A mass spectrometer provides evidence that different atoms of the same element have different atomic numbers.
E) Both c and d are correct.

Question

Quizplus · Accepted Answer

A mass spectrometer can be used to determine the isotopic composition of an element by measuring the mass-to-charge ratio of the ions produced during the analysis. Since isotopes of an element have different masses, a mass spectrometer can identify and measure the abundance of each isotope in a sample. Therefore, choice C is the most correct. Choices A, B, and D are incorrect because they do not accurately describe the role of a mass spectrometer in analyzing an element.
