   Ytterby          瑞典小镇伊特比


  yttrium        钇 (1794)
  erbium         铒 (1842)
  terbium        铽 (1842)
  ytterium       镱 (1907)
  1794年在瑞典小镇伊特比的黑石中发现了化学元素"钇",决定用 Ytterby命名该元素:yttrium。1842 年在该镇的黑石中发现了化学元素"铒", 决定用Ytterby 的第四、五、六、七个字母 erby 命名该元素:erbium。1842 年该镇的黑石中发现了化学元素"铒",决定用 Ytterby 的第、四、五、 六、 七个字母terby 命名该元素:terbium。1907 年又在该镇的黑石中发现了化学元素"镱",决定用 Ytterby 的全称命名该元素:ytterbium。这样,我们不但记住了这四种元素的英语名称,而且在需要时可做到脱口而出,书写无误。
