Currently the Periodic Table lists 118 elements.
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
Henry Moseley created current periodic table. Elements were arranged in order of atomic number.
About 2/3 of the Periodic Table of Elements is made up of Metals.
The periodic table is not expected to change significantly in the next 50 years. The organization and layout of the table are largely based on the atomic structure of elements, which is unlikely to change. Any additions of new elements will be accommodated by extending the table beyond its current layout.

Yes, there have been several versions of the periodic table developed over time. The current version is based on Dmitri Mendeleev's layout, which arranges elements by their atomic number and chemical properties. Different scientists have made adjustments and improvements to the periodic table as new elements have been discovered.

All together there are 118 elements on the periodic table, 94 of which occur naturally on earth. http://en.wikipedia.org/wiki/Periodic_table_%28standard%29 They do also show a wide format of periodic table with additional elements that have not been discovered, isolated, or synthesized on earth. http://en.wikipedia.org/wiki/Periodic_table_(wide)
118 including the Lanthanoids & Actinoids
The current periodic table is organized based on the atomic number of elements, which represents the number of protons in an atom. Elements are arranged in order of increasing atomic number from left to right and top to bottom on the periodic table.

Dmitri Mendeleev is known for creating the periodic table of elements. He arranged elements by increasing atomic mass and noticed patterns in their properties. His work laid the foundation for our current understanding of the organization of elements.
The current Periodic Table is organized by each elements atomic number. The atomic number is the number of protons in the nucleus of the atom of each element.
