The horizontal rows of the table are called periods. The elements of a period are characterized by the fact that they have the same number of electron shells; the number of electrons in these shells, which equals the element's atomic number, increases from left to right within each period. ...
The borders of the periodic table of the elements and of the chart of nuclides are not set in stone. The desire to explore the properties of atoms and their nuclei in a regime of very large numbers of electrons, protons and neutrons has motivated new experimental facilities to create new el...
In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
A quantitative relation between atomic electronegativity 蠂A and numbers P and G assigned, respectively, to the period and group of the corresponding element in the regular periodic table is reported. It is based on the rule of simple periodicity of the groups, whose application (the "periodic ...
The Periodic Table is a table of all the elements we know about today. Elements are placed in order of atomic number ( number of protons in the nucleus ).

Today, the periodic table organizes 112 named elements and acknowledges several more unnamed ones. It has become one of the most useful tools in chemistry, not only for students, but for working chemists as well. It classifies the elements according to their atomic number (more on that soon)...
