![]() Abundance of Elements in the Solar System |
The abundances of the elements in the solar system are usually estimated relative to the abundance of silicon. Since abundances vary widely, a logarithmic scale is used. We report here (number of atoms of the element in the solar system) Thus the relative solar system abundance of silicon would be log (1 E6) = 6. Values were obtained from "Abundances of the Elements: Meteoric and Solar ", by E. Anders and N. Grevesse, in Geochimica et Cosmochimica Acta, Vol. 53, pp. 197-214 (1989). |
