钻石和煤炭，竟是同一种东西？

Diamond looks bright and coal looks black. 钻石亮晶晶，煤炭黑乎乎。 But they are made of the same thing. 可它们俩，居然是同一种东西。 That thing is carbon, a common element. 这种东西叫碳，是一种常见元素。 In a diamond, carbon atoms line up neatly. 在钻石里，碳原子排得整整齐齐。 In coal, the atoms are messy and loose. 在煤炭里，原子却乱成一团。 Same atoms, but different order. 原子一样，只是排列方式不同。 One sells for a fortune, the other burns. 一个身价千金，一个拿来烧火。
