Unusual chemical symbols in English

Most chemical symbols look like a reasonable short form of the chemical element’s name in English – for example, C for carbon or Mg for magnesium. But there are 11 elements where the symbol doesn’t resemble the English name.

Note: The English names of many other chemical elements are originally from Latin or Greek, but they do correspond with the chemical symbol. In other languages (e.g. French), there is a different set of elements where the symbol doesn’t correspond with the name in that language.
