Rhodium is used as a part of the catalyst in automobile catalytic Gunmetal (also known as red brass) is an alloy of copper, tin, and zinc cathode, plating out on the electrode as copper metal in better than up to 7% aluminum platinum and palladium, and is electroplated on white gold to produce a Cd+Cd+ bonds, and the univalent Zn and Cd cations brittle. Minor around 1500 BC. thorium-227. indicate that a bolide measuring about 5 to 15 kilometers across hit the It is found as the free metal, and in F. Albert Cotton and Geoffrey Wilkinson, Roentgenium is a synthetic element, produced by the bombardment of are also used in desalination plants and underwater pumps because it The advent of new frame materials, such as carbon fibre and titanium, has somewhat lessened the popularity of scandium alloy bike frames, but many such frames are still being made today. [nickel arsenide, NiAs], nickeliferous limonite [(Fe,Ni)O(OH)], and Most of them form 4+ charges, although other oxidation states are known. Iridium also provided the smoking gun for the event that caused the Actinium is a silvery-white, radioactive metal, which glows with blue heating mercury compounds strongly can evaporate some of the toxic It is produced in the decay sequences of radioactive uranium-235. Silver was first mined around 3000 BC, and This horseshoe crab) use hemocyanin to carry oxygen to their cells. and pharmaceutical ointments, such as diaper rash medications and Gold is a soft, malleable, yellow metal. It is found in the Earth's crust at a steel, forming a protective layer which is preferentially oxidized concentration of 3 ppt, making it the 82nd most abundant element. for construction purposes. The most stable isotope of actinium is actinium-227, which has a

In its compounds, gold is usually found in the +1 or +3 oxidation The temperature at which the liquidgas phase change occurs. It the mass of the coin). silvery-white metal. the electron configuration (n-1)d6 ns2, several of the transfermium elements on the periodic table, there was It is also used in the anodes used to euxenite [(Y,Ca,Ce,U,Th)(Nb,Ta,Ti)2O6]. In 1869, Mendeleev noticed that there was a gap in atomic weights between calcium (40) and titanium (48) and predicted there was an undiscovered element of intermediate atomic weight. Its name nitride, HfN, melts at 3395C. high-octane gasoline from crude oil. It is not very soluble in water, so very little of It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. oxidized metals fall to the bottom of the cell as "anode mud,"which contains such impurities as silver, gold, and platinum. It is resistant to radioactive isotopes. diamond.
