Neodymium Silver Foil

See more Neodymium products. Neodymium (atomic symbol: Nd, atomic number: 60)is a Block F, Group 3, Period 6 element with an atomic weight of 144.242. The number of electrons in each of Neodymium's shells is 2, 8, 18, 22, 8, 2 and its electron configuration is [Xe] 4f⁴ 6s². The neodymium atom has a radius of 181 pm and a Van der Waals radius of 229 pm. Neodymium was first discovered by Carl Aer von Welsbach in 1885. In its elemental form, neodymium has a silvery-white appearance. Neodymium is the most abundant of the rare earths after cerium and lanthanum. Neodymium is found in monazite and bastnäsite ores. It is used to make high-strength neodymium magnets and laser crystal substances like neodymium-doped yttrium aluminum garnet (also known as Nd:YAG). The name originates from the Greek words neos didymos, meaning new twin.

The number of electrons in each of Silver's shells is 2, 8, 18, 18, 1 and its electron configuration is [Kr]4d¹⁰ 5s¹. The silver atom has a radius of 144 pm and a Van der Waals radius of 203 pm. Silver was first discovered by Early Man prior to 5000 BC. In its elemental form, silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. It is found in copper, copper-nickel, lead, and lead-zinc ores, among others. Silver was named after the Anglo-Saxon word "seolfor" or "siolfur," meaning 'silver'.
