IntermediateMCQConceptual24.5k
A student investigates the isotopic composition of a purified sample of neon gas using a mass spectrometer. In the instrument, neutral neon atoms are ionized to form singly charged cations, \(^{20}\text{Ne}^+\) and \(^{22}\text{Ne}^+\), accelerated through an electric field, and then directed into a magnetic deflection chamber. Which of the following correctly identifies the ion that undergoes greater deflection in the magnetic field and provides the correct justification?
