The periodic table of elements was invented by the Russian chemist Dmitri Mendeleev and nowadays it's the most common way to tabulate the elements.
The United States has the most elements on the periodic table.
Elements listed in the periodic table of elements are neutral; they do not have a charge. When they undergo chemical reactions they may become charged ions. There is no single most common charge for ions, but the most common are -1, -2, -3, +1, +2 and +3.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
about one third of the periodic table, but the most common are:carbonhydrogennitrogenoxygen
Metals / solids (around 75%)
The noble gases, column 18 in the most common modern periodic table.
Most of them are metals.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
