Calculate the atomic mass of sulfur if the four common isotopes of sulfur have masses of Calculate the atomic mass of sulfur symbol S , using data from the table below. Four isotopes of sulfur are sulfur, sulfur, sulfur, and sulfur Abundances for the first three isotopes are What is the average atomic mass of sulfur? Report the answer to five significant figures with units. Calculate the average atomic mass of sulfur if Sulfur has four naturally occurring isotopes, listed in the table below: Determine the number of neutrons for each isotope, and identify which isotope is the most abundant. Isotope Isotope mass u Naturally occurring europium Eu consists of two isotopes with a mass of and

Isotope Atomic mass Da Isotopic abundance amount fraction 32 S Isotopes of sulfur are fractionated by various chemical, physical, and biological processes. The major variations in the atomic weight of sulfur on earth are caused by kinetic isotope fractionations accompanying microbial oxidation-reduction reactions such as bacterial reduction of aqueous sulfate, in which the residual unreacted substrate is gradually depleted in the lighter isotopes, which react more rapidly. Over geologic time, processes such as these have resulted in major reservoirs of terrestrial sulfur with different atomic weights: oxidized forms such as marine sulfate commonly being heavy in comparison with the bulk earth and the majority of reduced forms such as organic sulfur and sulfide. The radioactive isotope 35 S is produced by cosmic-ray interactions with 40 Ar in the atmosphere and decays to 35 Cl with a half-life of 87 days. Sulfur was known as brenne stone for "combustible stone" from which brim-stone is derived.

For example, magnesium exists as a mixture of three isotopes, each with an atomic number of 12 and with mass numbers of 24, 25, and 26, respectively. These isotopes can be identified as 24 Mg, 25 Mg, and 26 Mg. They differ only because a 24 Mg atom has 12 neutrons in its nucleus, a 25 Mg atom has 13 neutrons, and a 26 Mg has 14 neutrons. Note that in addition to standard names and symbols, the isotopes of hydrogen are often referred to using common names and accompanying symbols. Hydrogen-2, symbolized 2 H, is also called deuterium and sometimes symbolized D. Hydrogen-3, symbolized 3 H, is also called tritium and sometimes symbolized T.
