Do the names of chemical elements need to be capitalized?

For example, in running text should it be hydrogen or Hydrogen?

Not capitalized. Not even einsteinium, curium, and so on. –  GEdgar Oct 6 '13 at 22:05

While chemical symbols always begin with a capital letter, the names of chemical elements do not. In running text, you should be writing H, O, Cl, Fe, etc, but hydrogen, oxygen, chlorine, iron, etc. should not be capitalized.

That is what happens with the physics units: joule, watt, erg, etc. –  kiamlaluno Oct 12 '10 at 15:02

Elements are common nouns. So the answer is no.
