But the polymer falls apart almost as easily as it forms, making it useless for practical applications. But this polymer phase gave the researchers a window to "throw in something, potentially, that it would react with" to stabilize the plastic, Pyun said. Fortunately for the team, one of the first chemicals they tried turned out to be a winner: 1 3-diisopropylbenzene, easier known as "DIB. The result, as the researchers reported in April in the journal Nature Chemistry, was a red plastic that doesn't even smell like rotten eggs — the polymerizing sulfur is not volatile, Pyun said, and thus doesn't reek like the volatile sulfur compounds one might find at a hot springs.
Even better, the process is so simple that Pyun and his colleagues call it "cave man chemistry. The team has been approached by several companies interested in taking the sulfur polymerization process commercial. Which could be good news for the environment. Conventional oil and gas reservoirs are about 1 to 5 percent sulfur, Pyun said. More and more, however, oil and gas exploration is tapping into unconventional reservoirs filled with nastier stuff: The oil from tar sands in Alberta, Canada, is 20 percent sulfur.
Some new fields in the Middle East produce oil that is up to 40 percent sulfur, Pyun added. With any luck, his team's process can turn that garbage into something useful.
Elemental sulfur is a commonly used pesticide on many American and European farms. It is approved for use on both conventional and organic crops to help control fungus and other pests. In California alone, more than 21 million kilograms Previous Element Phosphorus.
Next Element Chlorine. What's in a name? From the Sanskrit word sulvere and the Latin word sulphurium. Sulfur, the tenth most abundant element in the universe , has been known since ancient times. Sometime around , Antoine Lavoisier convinced the rest of the scientific community that sulfur was an element. The majority of the sulfur produced today is obtained from underground deposits, usually found in conjunction with salt deposits, with a process known as the Frasch process.
The damaging effects of sulfur with animals are mostly brain damage, through malfunctioning of the hypothalamus, and damage to the nervous system. Laboratory tests with test animals have indicated that sulfur can cause serious vascular damage in veins of the brains, the heart and the kidneys. These tests have also indicated that certain forms of sulfur can cause foetal damage and congenital effects.
Mothers can even carry sulfur poisoning over to their children through mother milk. Finally, sulfur can damage the internal enzyme systems of animals. Back to the periodic table of elements. For more information on sulphur's place in the environment, move to the sulphur cycle.

These blocks are named for the characteristic spectra they produce: sharp s , principal p , diffuse d , and fundamental f. Atomic number The number of protons in an atom. Electron configuration The arrangements of electrons above the last closed shell noble gas. Melting point The temperature at which the solid—liquid phase change occurs. Boiling point The temperature at which the liquid—gas phase change occurs.
Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. Relative atomic mass The mass of an atom relative to that of carbon This is approximately the sum of the number of protons and neutrons in the nucleus.
Where more than one isotope exists, the value given is the abundance weighted average. Isotopes Atoms of the same element with different numbers of neutrons. CAS number The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Murray Robertson is the artist behind the images which make up Visual Elements. This is where the artist explains his interpretation of the element and the science behind the picture.
Where the element is most commonly found in nature, and how it is sourced commercially. Atomic radius, non-bonded Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced.
These values were determined using several different methods. Covalent radius Half of the distance between two atoms within a single covalent bond. Values are given for typical oxidation number and coordination.
Electron affinity The energy released when an electron is added to the neutral atom and a negative ion is formed. Electronegativity Pauling scale The tendency of an atom to attract electrons towards itself, expressed on a relative scale. First ionisation energy The minimum energy required to remove an electron from a neutral atom in its ground state. The oxidation state of an atom is a measure of the degree of oxidation of an atom.
It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Data for this section been provided by the British Geological Survey. An integrated supply risk index from 1 very low risk to 10 very high risk. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.
The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply. The availability of suitable substitutes for a given commodity. The percentage of an element produced in the top producing country. The higher the value, the larger risk there is to supply. The percentage of the world reserves located in the country with the largest reserves.
A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators.
Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. A measure of the stiffness of a substance. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. A measure of how difficult it is to deform a material. It is given by the ratio of the shear stress to the shear strain. A measure of how difficult it is to compress a substance. It is given by the ratio of the pressure on a body to the fractional decrease in volume.
A measure of the propensity of a substance to evaporate. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system.
