There can be no doubt that any science student who is interested in chemistry must learn the periodic table. But just learning the periodic table is not really enough. It is a merely first step before going deeper into it. The next step would be to add the ionic charges, the full names, and mass of each of the ...
POC isn't shy about design. Much like the Swedish company's standout helmets, the POC DO Half Blade sunglasses are hard to miss. Regardless of how they look from the outside — some of us at BikeRadar like the aesthetics, others don't — the half-frame sunglasses work well on the bike. Here's why.
Within an hour, you'll barely have any Bohrium left. This gets annoying fast. One of the newly added elements, Ununtrium, has a half-life of only 20 seconds. Ununoctium, another new element, takes less than one millisecond to decay by half. It hardly exists at all. On one hand, this is an incredible story ...
They were added to the Periodic Table in January 2016, to the seventh row, after the likes of bohrium, hassium and copernicium. And they're all very radioactive; the most stable isotope of the one with 115 protons in its nucleus has a halflife of 220 milliseconds. What are their names? By the number of ...
Both elements take Russian names: moscovium is for Moscow, while oganesson is named for living physicist Yuri Oganessian, leader of the Russian team and contributor to lots of elements' discoveries, including flerovium, bohrium, seaborgium, and dubnium. Tennessine is named for Tennessee, since ...
In the end, the IUPAC decided that the US could have elements 104 (rutherfordium) and 106 (seaborgium), Russia would be awarded 105 (dubnium) and 107 (bohrium), and Germany got the naming rights to 108 (hassium) and 109 (meitnerium). That decision was taken in 1997 and the refreshed naming ...
This week's element is roentgenium, which has the atomic symbol, Rg, and atomic number, 111. Originally known by its temporary name, unununium (Uuu -- which is my favourite atomic symbol that is associated with any of the elements' temporary names), this element was named in honour of German ...
As with all the other super-heavy transactide elements we've been learning about these past few months, bohrium is a radioactive synthetic element that only is found in a laboratory, and even then, its half life is so short that there's little chance that it might ever escape. However, if we had the chance to ...
... decays to the following daughter isotopes: Roentgenium-274; Meitnerium-270; Bohrium-266; Dubnium-262; Lawrencium-258; and Mendelevium-254. ... a heavy isotope of element 113, to isotopes of relatives Roentgenium (111); Meitnerium (109); Bohrium (107); Dubnium (105); Lawrencium (103); and ...
