Periodic table - Elements, Groups, Properties: The noble gases—helium, neon, argon, krypton, xenon, radon, and oganesson—have the striking chemical property of forming few chemical compounds. This property would depend upon their possessing especially
The alkali metal family includes the six elements in thefirst columnof the periodic table, fromlithium(Li) down to francium (Fr). These metals all contain one valence electron, meaning they form cations and react readily with water. These elements form the ionic bonds known as salts. Hydrogen...
" moment that led Mendeleev to the sorting strategy of the complete periodic table is still shrouded in mystery. "It is extremely difficult to reconstruct the process by which Mendeleev came to his periodic organization of elements in terms of their atomic weights," Gordin wrote of the full per...
John Newlands was an English chemist whose “law of octaves” noted a pattern in the atomic structure of elements with similar chemical properties and contributed in a significant way to the development of the periodic law. Newlands studied at the Royal
including the post-transition metals and metalloids. Examining how these elements are synthesized in the universe, when and how they were discovered, and where they are found on Earth, this new, full-color resource clearly details how ...
Finally, in 1869, the German Lothar Meyer and the Russian chemist Dmitry Ivanovich Mendeleev almost simultaneously developed the first periodic table, arranging the elements by mass. However, Mendeleev plotted a few elements out of strict mass sequence in order to make a better match to the ...

In this article, we'll break down everything you need to know about the periodic table. From its history and layout to its key elements and groups
So now the students and the users don’t have to worry because we are bringing you the table and the table will not only have the elements in but just below that it will have the name and number and also the details of a particular element. ...
These values are calculated using self-consistent-field functions (reference 1). You should consult reference 1 for full details, but it is not light reading for most people. There is a correlation between the atomic radii as determined from these calculations and the radii of maximum charge den...
