Aluminum is highly reactive ... in nature it is found primarily in the form of insoluble oxides and silicates.

So of course I looked up elements in the earth's crust. #1 is oxygen, representing almost half the earth's crust at 461,000 ppm.

And now I have a sinking feeling that I'm walking on air.
