Interactive Periodic Table of Elements
Argon Ar , chemical element , inert gas of Group 18 noble gases of the periodic table , terrestrially the most abundant and industrially the most frequently used of the noble gases. Colourless, odourless, and tasteless, argon gas was isolated from air by the British scientists Lord Rayleigh and Sir William Ramsay. His work was forgotten until Lord Rayleigh, more than a century later, found that nitrogen prepared by removing oxygen from air is always about 0.

Element 38 in our International Year of the Periodic Table series is strontium. Named after Strontian, a village in Scotland where it was discovered, strontium finds use in glow-in-the-dark paints and in toothpastes. Element 37 in our International Year of the Periodic Table series is rubidium. Used in GPS satellites and in some types of perovskite solar cells, one of its isotopes can also be used to locate and image brain tumours.

The story of the fifteenth element began in Hamburg, in Instead, he distilled something new. It was foamy and, depending on the preparation, yellow or black. Interested parties took a look; some felt that they were in the presence of a miracle. At first, no one could figure out what the Prometheus of Hamburg had stolen. The soapy phosphorus that Brandt cooked up was a curiosity.
But, in England, Boyle began producing it in a purer, more solid form, which turned out to be highly flammable. The phosphorus industry grew throughout the eighteenth century, in part because physicians wrongly believed that it had medicinal value. In the eighteen-hundreds, match producers found that wood splints tipped with phosphorus were less dangerous than their sulfur-coated predecessors; not long afterward, the discovery that electric furnaces could extract phosphorus from ore at a large scale led to the development of explosives.

If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph. Text search:. It is attributed by them to Nechaev and is apparently discussed by Ipatiev :. We would also like to mention one more version of the periodic table, namely the one offered by V. Ipatiev’s version was one of the first to have been applied in a school textbook, and is also concise and accompanied by a detailed methodological commentary.

As the Azure lead at Data 3, I have the impossible task of keeping up-to-date with everything Azure. I need to know and understand how each of the discreet service offerings in Azure work from both a technical and business capability perspective. You can get a sense of the sheer scale of services available in Azure by looking at this list of Azure Products from Microsoft. I use many technology resources to assist me with information and news to keep up to speed, including my Azure news bot that scrapes relevant RSS feeds and posts to our internal Microsoft Teams and Yammer sites for new and exciting Azure updates.
My bot can frequently post up to 20 announcements such as those below a week, so there is literally an endless stream of Azure changes, innovations and news to stay across. Needless to say, our customers are busy — they have a business to run and IT operations and project teams have a full-time day job helping the business deliver and innovate. Time to research and keep up with all things Azure is limited and this often leads to mistakes.

A century and a half ago, Dmitri Mendeleev published an organisation of the elements that had been discovered at that point. His chart made sense — listing the elements in order of increasing atomic mass, looping to a new list when their properties started to repeat. This year, the periodic table of the elements celebrates its th birthday. Image reference of a pillar and symbol of science. You see, expanding the periodic table is no small feat. Making a new element takes bashing together other atoms at just the right incredibly high speed.
Just getting the collision to happen at all is tough enough, but even then, the new element known as a superheavy element, or SHE, after their huge atomic mass might only exist for a fraction of a fraction of a second 10 -4 seconds, according to eminent theorist John Wheeler. The last batch of four new elements, accepted by the International Union of Pure and Applied Chemistry IUPAC in , was the work of over a hundred scientists in four separate teams over countless hours.
Curiosity suffices for some. As we strive to find new elements, we unlock more and more information about the physics at the smallest of scales. Superheavy elements are so heavy that they start to show all sorts of wacky behaviour. In particular, their electrons move much faster than those of lighter elements, so that relativity starts to play an important role.

Don’t have a profile? The periodic table of the elements was first introduced in the midth century by Dmitry Mendeleev. Its interactive features allow you to easily view the atomic number along with other important properties of all elements by clicking on the periodic chart. You may also use the color-coded periodic table chart with names, symbols, and atomic weights to find specific information you need for your work.
Easy-to-use filters allow you to sort by metals, nonmetals, physical states, group, period, and more. For your convenience, we also offer a printable periodic table of elements.
