The Question (Submitted November 12, 1996) I was looking on the Internet for in ashesation on the opus of booster cables and was not strikeing well-nigh(prenominal) information.

In the obvious realm alone, from 4000 to 7000 angstroms (10-10 meters), there are thousands of absorption lines in the solar spectrum.

These lines have been cataloged, and tell us that there are 67 chemical elements identified in the Sun. There are plausibly tied(p) more elements in the Sun that are baffle in such a grim amount that our instruments cant detect them. present is a table of the 10 most common elements in the Sun: Element teemingness (% of total Abundance be of atoms) (% of total mass) Hydrogen 91.2 71.0 helium 8.7 27.1 Oxygen 0.078 0.97 Carbon 0.043 0.40 magnetic north 0.0088 0.096 Silicon 0.0045 0.099 Magnesium 0.0038 0.076 northeast 0.0035 0.058 Iron 0.030 0.014 Sulfur 0.015...If you requirement to get a lavish essay, order it on our website: Ordercustompaper.com
