In the ion source, the sample is injected into the induction heating coil where it is partially ionized. The ions are then accelerated with an electrostatic potential through skimmer cones and collimated into a beam. The kinetic energy that a singly positively charged 202Hg ion acquires during this acceleration is approximately how much larger or smaller than the kinetic energy of a similarly charged 208Pb ion

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
