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
Mendeleev’s introduction of the periodic table of elements is one of the most important milestones in the history of chemistry, as it brought order into the known chemical and physical behaviour of the elements. The periodic table can be seen as paralle
15. Finally, fill the 6p orbitals with the remaining electrons: 6p6.Putting it all together, the electron configuration for radon is:Rn: 1s22s22p63s23p64s23d104p65s24d105p66s24f145d106p6Radon is located in Group 18 (VIII A) and Period 6 of the periodic table. I...

1 through 18, are called groups. In the periodic table, elements with similar chemical properties are in the same group. The horizontal rows of the periodic table, from 1 to 7, are called periods. Periods correspond to the number of electron shells possessed by atoms of the elements in tha...
