J. At the top of each Element page is a periodic table, which allows one to quickly move to other elements’ pages. Figure \(\PageIndex{1}\): A Modern Periodic Table. The Table of Contents on the right column helps the user to readily locate desired information. We also thank the members of the Committees on Computers in Chemical Education (CCCE) for providing valuable feedback about PubChem resources. Therefore, PubChem has a great potential as an online resource for chemical education. We then create plots of Melting Point/Boiling Point vs. Atomic Number. Kim, S.; Thiessen, P. A.; Bolton, E. E.; Chen, J.; Fu, G.; Gindulyte, A.; Han, L. Y.; He, J. E.; He, S. Q.; Shoemaker, B. Look up chemical element names, symbols, atomic masses and other properties, visualize trends, or even test your elements knowledge by playing a periodic table game! With 3.5 million unique users per month at peak, it is considered as one of the top five chemistry web sites in the world in terms of web traffic. IUPAC International Year of Periodic Table 2019. https://pubchem.ncbi.nlm.nih.gov/element/9#section=History. 3. What makes the Periodic table really invaluable is … Am. https://www-nds.iaea.org/amdc/ (accessed 5/2/2019). The periodic table in its present form is considered to be first introduced in 1869 by a Russian chemist, Dimitry Mendeleev, although there had been earlier attempts to classify elements by their similarities. Chem. These new services help users navigate the abundant chemical element data available within PubChem, while providing a convenient entry point to explore additional information, such as bioactivities and health and safety data, available in PubChem Compound pages for specific elements and their isotopes. I was asked about the discrepancy in the year of discovery for some elements between the PubChem Periodic Table and Wikipedia data. NCBI and PubChem are celebrating the 150th anniversary of the periodic table of chemical elements, one of the most recognized tools in science. Without it, chemistry would be a chaotic, confusing jumble of seemingly random observations. The PubChem Periodic Table and Element pages help users navigate the abundant chemical element data available within PubChem, while providing a convenient entry point to explore additional information, such as bioactivities and health and safety data, available in PubChem Compound pages for specific elements and their isotopes. •          The Game View (https://pubchem.ncbi.nlm.nih.gov/ptable/#view=game), added as an educational feature, helps test one’s knowledge of element names and symbols. With that said, PubChem does not fix the incorrect/misleading data that it does not own. Robert is right that scholars (including students) should only cite sources that they have actually consulted. Lawrencium is a chemical element with symbol Lr and atomic number 103. The PubChem member who collected the year of discovery data told me that he picked most agreed value among the three sources in the history section for each element, and if there is no clear agreement, he picked the year provided by the Jefferson lab. Oxidation States +3. To join the discussionemail the site administratorBob Belford rebelford@ualr.edu. PubChem is a public chemical information resource, developed and maintained by the U.S. National Institutes of Health. All authors read and approved the final manuscript. . 4. I think you have brought up two very important points that students often miss. 94 of the 118 chemical elements on the periodic table occur naturally. H: 103. AG generated the user interface. 15. International Atomic Energy Agency - Nuclear Data Section Atomic Mass Data Center (AMDC). •          The List View (https://pubchem.ncbi.nlm.nih.gov/ptable/#view=list) allows one to see a set of properties available for each element all at once. We are thankful for the overall efforts of the entire PubChem team and other teams throughout NCBI, without of which this work would not be possible. In that case, it is highly recommended to visit the original data sources to check the context (or metadata) of the data. Because of this dynamic default, you will see the List View on the mobile device and the table view on a large moniter connected to a Mac/PC. 10. The element page can also be reached directly via URLs that includes atomic number, symbol, or name (all case-insensitive). If you compare the year of discovery between the two sources, you will see that some elements indeed have discrepancies (+/- 1 year for some, but often more than +/-30 years for others). Using the search box at the top-left corner, one can quickly find an element of interest. Allred, A. L., ELECTRONEGATIVITY VALUES FROM THERMOCHEMICAL DATA. J. Sodium nitrate (NaNO 3) and potassium nitrate (KNO 3) are formed by the decomposition of organic matter with compounds of these metals present.In certain dry areas of the world these saltpeters are found in quantity and are used as fertilizers. The game has three levels of difficulty (easy, medium, and hard). For a wider window, the Table view is the default. In 1827, Berzelius and Osann examined the residues left after dissolving crude platinum from the Ural mountains in aqua regia. https://pubchem.ncbi.nlm.nih.gov/ptable/#view=table&property=YearDiscovered (PubChem P-Table)https://en.wikipedia.org/wiki/Timeline_of_chemical_element_discoveries (Wikipedia). This year gap is often larger than 100 years (for example, for fluorine, fluorine compounds were reported as early as back in 1670, but fluorine was isolated in 1886 (216 years later), as explained in here. 2016, 88, 293-306. Educ. The Royal Society of Chemistry’s interactive periodic table which includes Murray Robertson’s Visual Elements artwork. 1964, 41, 3199-3204. SK wrote the initial draft and SK, AG, JZ, PT, and EB revised it. One of the PubChem scientists have read these paragraphs to collect the year of discovery for each element. The PubChem Periodic Table can be accessed by clicking the Periodic Table icon (indicated with the green box). The data presented on the Element page can be downloaded using the “Download” button at the top-right corner. Snapshot of the Game View of PubChem Periodic Table (https://pubchem.ncbi.nlm.nih.gov/ptable/). Opin. The periodic table of chemical elements is one of the most recognized tools in science. Journal of Inorganic & Nuclear Chemistry 1961, 17, 215-221. Other inorganic nitrogen compounds are nitric acid (HNO 3), ammonia (NH 3), the oxides (NO, NO 2, N 2 O 4, N 2 O), cyanides (CN-), etc. B.; Meek, T. L.; Allen, L.

If you use PubChem to find some data and stop there, you cite PubChem, but if you see some discrepancies in the data within PubChem, you will need to check individual data sources to what the data actually mean and cite the source of the data that you believe is most appropriate. Expert. To learn more about this, please read this post (https://go.usa.gov/xmUQ9). http://ciaaw.org/ (accessed 5/2/2019). 13. If you go to the Pubchem periodic table and click "standard state, you will see 2 elements are liquid, 11 are gasses, and one (Og) is "expected" to be a gas. https://www.nist.gov/pml (accessed 5/2/2019). Classified as an actinide, Lawrencium is a solid at room temperature. Figure 2. The PubChem Periodic Table provides three distinct views: Table View, List View, and Game View. J. Chem. If they follow Bob's advice to check on the data given in Wikipedia or PubChem by going to that source, then they ought to cite that source—and they can ethically do so because they will have consulted it to verify it. The PubChem Periodic Table is a public service and, if you want, you can embed it within your web page for free, using the iframes (as you mentioned). Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
