Question

answer the following questions to determine what nanoscale species are moving through a mass spectrometer during its operation. a mass spectrometer is an instrument that measures the mass of atoms and molecules. a gas sample is placed in the chamber and bombarded by a beam of particles. what are these particles? options: electrons, protons, neutrons

Explanation:

In a mass spectrometer, the gas sample is ionized by bombarding it with electrons. Electrons are used to knock electrons off the atoms or molecules in the gas sample, creating ions. Protons and neutrons are not typically used for this bombardment process in a mass spectrometer's ionization step.

Answer:

A. Electrons
