Hence, the atomic radius of magnesium, strontium and calcium is 150 pm, 200 pm and 180 pm respectively. Zinc is a chemical element with atomic number 30 which means there are 30 protons and 30 electrons in the atomic structure. What are the lengths a, b, and c for the unit cell for magnesium? A solid chunk of material has many atoms, and they are arranged in certain ways and sometimes more than one way of this arrangement is possible. Atomic radii decrease, however, as one moves from left to right, across the Periodic Table. In sodium, a valence electron is being attracted, pulled inward, by 11 protons. The chemical symbol for Polonium is Po. Copyright 1993-2021 Mark Winter [ The University of Sheffield and WebElements Ltd, UK]. Discoverer: Davy, Sir H. and Thénard, L.-J. ANSWER (2) (Total 6 marks) 7. Pure radium is silvery-white alkaline earth metal. Although neodymium is classed as a rare earth, it is a fairly common element. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Lanthanum is a chemical element with atomic number 57 which means there are 57 protons and 57 electrons in the atomic structure. Note: All measurements given are in picometers (pm). Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium.
