There are 91 natural elements. These can be found naturally everywhere in the world. However, new elements have been artificially made in a laboratorium. So far, 27 elements have been made by humans, leaving a total of 118 elements on the Periodic Table. However, these synthetic elements can't be considered real elements, since they disappear almost as fast as they were made. For instance, ununoctium's (element number 118) most stable isotope has a half-life of 0.00089 seconds. But in the Extended version of the periodic table it goes all the way up to element 173 but no research has been found yet.....

Actually, there are 117 elements on the periodic table. But, they couldn't make element number 117 so it's 1-116 and then 118.
There are 118 elements in the periodic table (March 2013).
By grouping the elements on the Periodic Table.
See the link below fot the IUPAC model of the periodic table of elements.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Most of the elements on the periodic table are metals.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
there are precisely 118 elements on the periodic table.
There are 53 Elements in the Periodic Table.
A Periodic table The Periodic Table of the Elements.
The Periodic Table has 118 elements and counting...
It's 118 chemical elements in the periodic table.

The periodic table of elements does not contain laws, only elements.
There are 118 elements on the periodic table.
118 chemical elements are now in the periodic table.
There are 18 groups in the periodic table of elements.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
There are 117 elements on the periodic table, however, there is one blank spot that lies on the periodic table of elements, it has the atomic number of 117. If it were discovered, there would be 118 elements on the periodic table of elements.
