Use the data to identify and explain which radiation comes from sources X, Y and Z. An unstable nucleus will decompose spontaneously, or decay, into a more stable configuration but will do so only in a few specific ways by emitting certain particles or certain forms of electromagnetic energy. used to identify the hardness of minerals. Although thousands of minerals in the earth have been identified, just ten minerals make up most of the volume of the earth's crustplagioclase, quartz, orthoclase, amphibole, pyroxene, olivine, calcite, biotite, garnet, and clay. Autunite is a radioactive orthorhombic mineral which results from the hydrothermal alteration of uranium minerals. Record the weight displayed on the scale. Step 12: Crystal Shape (Habit) If your mineral sample has some even crystal faces or is a well-formed crystal, observe it attentively. Specific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water.
