Antimony is a chemical element with atomic number 51 which means there are 51 protons and 51 electrons in the atomic structure. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. Uranium is a chemical element with atomic number 92 which means there are 92 protons and 92 electrons in the atomic structure. The density of potassium, which has the BCC structure, is … It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the prototype. Licenses and Attributions: . 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. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins. Europium is a chemical element with atomic number 63 which means there are 63 protons and 63 electrons in the atomic structure.
