The rare earth that paints welder goggles green and lurks in your magnets.
means A soft, silvery rare-earth metal (element 59, symbol Pr) used in welding-goggle glass, powerful magnets, and lighter flints.
from Greek through and through: 'prasios' (leek-green, for its salts' color) plus 'didymos' (twin). The 'didymium' part is the giveaway — in 1841 a substance was named didymium, the 'twin' because it stubbornly shadowed lanthanum and refused to be separated. Half a century later it was unmasked as not one element but two, and the green-tinged twin became praseodymium — literally 'the green twin.'
