Copyright © Science Struck & Buzzle.com, Inc. 1.1.2 Medical Uses. A horizontal row in the periodic table. It was discovered by Swedish chemist, Lars Fredrik Nilson, in the year of 1879. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry. Scandium in the environment. The radioactive isotope scandium-46 is used as a tracer in oil refining to monitor the movement of various fractions. Scandium is used to make high intensity lamps. Certainly scandium's applications speak for themselves in terms of importance. This is approximately the sum of the number of protons and neutrons in the nucleus. The image reflects this with an ancient Scandinavian figurine and carved runic standing stone. Scandium is usually found only in two different kinds of ores. Scandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. Therefore, … Health effects. The electron configuration for scandium is: $$\ce{1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1}$$ The $\ce{4s}$ and $\ce{3d}$ orbitals are relatively close in energy, so there are a few anomalies in the order of filling. Compounds. Putting the scandium from rare earth occurrences in iron aside, modern analytical chemistry has also found that scandium is frequently (probably always) found as a trace in niobium deposits.
