There are 14 general types of such patterns known as Bravais lattices. Discoverer: Davy, Sir H. and Thénard, L.-J. Polonium is a chemical element in the periodic table that has the symbol Po and atomic number 84. It has 84 protons and 84 electrons in the atomic structure. While resistivity is a material property, resistance is the property of an object. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. Discoverer: Marinsky, Jacob A. and Coryell, Charles D. and Glendenin, Lawerence. Electrical resistance is expressed in Ohms. To understand the difference between metals, semiconductors and electrical insulators, we have to define the following terms from solid-state physics: A possible crystal structure of Polonium is rhombohedral structure. Polonium Element-Polonium is a chemical element in the p-block, 16 th group and 6 th period of periodic table. Polonium-210 has a half-life of 138.39 days.
