WebIn 1794, Gadolin announced that it contained a new 'earth' which made up 38 per cent of its weight. It was called an’ earth’ because it was yttrium oxide, Y2O3, which could not be reduced further by heating with charcoal. The metal itself was first isolated in 1828 by Friedrich Wöhler and made by reacting yttrium chloride with potassium.
WebMost molecules are so small they are measured in units such as nanometers or micrometers, but sizes can range anywhere from 10 -10 m for molecular hydrogen, the smallest molecule, up to 5 cm in the case of a human DNA strand (if it were uncurled).
