What I mean was this: except those elements whose names are also common words in everyday language, like iron, copper, silver, etc. all the other elements's names are foreign to the general public. Like Neodymium, Samarium, etc, even if general public can pronounce them, they don't really know what they are. This applies to chemical compounds, like those listed as ingredients in packaged food, as well. It doesn't matter it is in Chinese or in English. The general public don't know what they really are.
