Sixth transition metal

Webb22 okt. 2024 · A brittle, hard, transition metal that shared a silvery-white appearance with platinum, iridium is the second densest metal following osmium. Iridium is used primarily in electronics such as spark plugs and electrodes. Devices that need to withstand against extreme temperatures are usually made of iridium. 1. Osmium 22.6 g/cm^3 This period contains the lanthanides, also known as the rare earths. Many lanthanides are known for their magnetic properties, such as neodymium. Many period 6 transition metals are very valuable, such as gold, however many period 6 other metals are incredibly toxic, such as thallium. Period 6 contains the last stable element, lead. All subsequent elements in the periodic table are radioactive. After bismuth, which has a half-life or more than 10 years, polonium, astatine, and rad…
