| Element | % mass |
|---|---|
| Oxygen | 46.71 |
| Silicon | 27.69 |
| Aluminum | 8.07 |
| Iron | 5.05 |
| Calcium | 3.65 |
| Sodium | 2.75 |
| Potassium | 2.58 |
| Magnesium | 2.08 |
| Titanium | 0.62 |
| Hydrogen | 0.14 |
| Phosphorus | 0.13 |
| Carbon | 0.09 |
| Manganese | 0.09 |
| Sulfur | 0.05 |
| Barium | 0.05 |
| Chlorine | 0.05 |
| Chromium | 0.04 |
| Fluorine | 0.03 |
| Zirconium | 0.03 |
| Nickel | 0.02 |
Notable missing from top 20:
Copper.
Carbon might replace copper for many electrical (and thermal) conduction applications - see [1], [2] and carbon nanotube 
for further information. In September 2013, a proof-of-concept computer was built from carbon nanotubes [3]
Figures from [4]
Figures rounded to two decimal places
