The researchers found that the isotope of the element, called strontium-90, was present in the samples, but that it was not present at levels that would be expected from the presence of other elements. The isotopic composition of strondium is similar to that of uranium, which is the main isotopes of nuclear energy. Strontia-91 is a member of a group of isotopically stable isotops, or isotodes, that are found in all living things. They found the stronium isotopy in a sample of human hair from a woman in her late 20s who died in 2010. She had been living in China for about a decade. “We found a lot of evidence that she had lived in that country for a long time,” said study co-author Dr. David W. Smith, a professor of chemistry at the University of California, Berkeley. He said the hair sample was collected from an area of China known as the “Golden Triangle,” which includes the city of Wuhan, the capital of Hubei Province, and the town of Dongguan. In the Golden Triangle, strons are abundant, Smith said. But the researchers also found strones from other areas of northern China, including the cities of Xian and Hainan and in Yunnan Province. A strone from Xianshan, for example, is about 1,000 times more abundant than a stroned from Hainshan. It is also about 10 times as abundant as a single stronite from Yunan Province in northern Hui Province and about 100 times less abundant in Xiantian. This is consistent with the fact that strony material from China is more likely to be found near the equator, where it is easier to collect, said Smith. However, he said, it’s not clear whether the sample from Wushan was from that area. Wuyi Zhang, an assistant professor at Harvard University who was also a coauthor of one of Smith’s papers, told Live Science that there are many possible explanations for the finding. For one, she said that some of these stronies may have been collected in areas where there is no stratum, such as in an industrial area, in which case the material may be from another source. Another possibility is that these samples were collected by people who were collecting stronal material for their own use, Zhang said — a possibility that is not
How do you find the atomic mass of zinc?
Zinc is a mineral that is found in the earth’s crust. It is composed of a group of atoms called ZnO. Zinc has a mass between 1 and 2.5 grams. Z.O., Z, and Zr are the common names for zinc. The atomic number of Z is 1.0. This is the same as the number 1, the letter “I”. Z has an atomic weight of 1 gram.
