For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
Type: Halogen Atomic weight: 35.453. Density @ 293 K: 0.003214 g/cm3 Atomic volume: 22.7 cm3/mol. Discovered: Chlorine was produced first in 1774 by Carl Wilhelm Scheele, who observed the greenish-yellow gas released by the reaction of pyrolusite (manganese dioxide) with the substance we now call hydrochloric acid.
