The article gives examples of trends in properties of the elements, their ions, and their compounds, which can usefully be examined from the perspective of the periodic table as a whole, rather than by looking a

In this lab, students compared the periodic trends of the elements in comparison to the atomic number. A periodic trend is the tendency of certain properties of the elements to increase or decrease as one progresses along a row or column of the periodic table. The periodic table is arranged ...
The periodic table can be seen as parallel to the Standard Model in particle physics, in which the elementary particles known today can be ordered according to their intrinsic properties. The underlying fundamental theory to describe the interactions between particles comes from quantum theory or, ...
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...
Periodic Trends Elemental Properties and Patterns I CAN use the PT to predict a number of properties among the elements. The Periodic Law Though he didn’t realize it at the time, Mendeleev made an important discovery about the elements. Mendeleev’s repeating patterns on his Periodic Table led...
The periodic table of Mendeleev, initially proposed on the basis of 66 elements, and containing 82 elements at the time of Moseley (1887–1915), describes nowadays 118 elements. The huge challenge of this scientific adventure was, and still is, the development of technologies and methods capable...
This periodic table depicts not only the trends of nuclear properties, but also reproduces their numerical values that remain very close to the experimental values (difference less than 4%). The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. It is like ...
