Some elements are desperate to do that and they are very reactive; others, like the noble gases or gold or platinum, not so much. It all boils down to thermodynamics ...

In this periodic table of elements quiz, you have 10 minutes to name as many elements as you can, given only their symbol, atomic weight and the broad group they live in. It's no mean feat, the ...

Periodic Table Chemistry: Get here the complete information on the periodic table of elements along with the easy tricks to remember their names. Check who invented the modern periodic table and ...

Oddly, though, at temperatures between these two, the element doesn’t react. Oganesson is grouped in the periodic table with the noble gases, but researchers think it is neither noble nor a gas.

The elements on the periodic table of elements are listed in ways that emphasize certain relationships. There are families, periods (the horizonal rows) and groups (the vertical columns).

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore ...

When argon was discovered in 1894, it didn’t fit into any of Mendeleev’s columns, so he denied its existence — as he did for helium, neon, krypton, xenon and radon. In 1902, he acknowledged he had not ...

For one thing, the modern table has a bunch of elements that Mendeleev overlooked (and failed to leave room for), most notably the noble gases (such as helium, neon, argon).

Anyone who attended a high school science class can probably conjure an image of the periodic table of elements, an imposing array of multicolored rows and columns that sorts all the known chemical ...
