Question

An inert gas such as xenon is used to accomplish this task in fast atom bombardment. For 10 points each:
[10h] Identify this process, which follows matrix-assisted laser desorption in one technique. This process is classified as either “hard” or “soft” based on the amount of fragmentation.
ANSWER: ionization [accept word forms or equivalents like forming ions; accept matrix-assisted laser desorption/ionization or hard ionization or soft ionization]
[10e] Ionization is the first step of a form of spectrometry named for this quantity that measures its ratio to charge. Daltons are the unit used to report atoms’ value of this quantity instead of grams.
ANSWER: mass [accept mass spectrometry; reject “weight”]
[10m] The calutron, an early mass spectrometer, was designed to help separate this element’s isotopes. This element’s “depleted” form contains almost none of its 235 isotope.
ANSWER: uranium [or U; accept depleted uranium]
