it changes because you 50 years in 2013 it will change you will see
The periodic table may change over time as new elements are discovered or as our understanding of atomic structure evolves. New elements can be added to the table, and their properties may lead to a reorganization of the elements. The overall layout and concepts of the periodic table are likely to remain consistent, but the specific details can change.
No, because as the days and years go past, more scientists will find out more information on the periodic table. When they find out information on the periodic table, sometimes new elements are found, adding new elements on the periodic table causes it to change.
The periodic table is unlikely to change significantly in the next ten years as the fundamental properties of elements remain constant. However, new elements may be discovered and added to the table if they meet the criteria set by the International Union of Pure and Applied Chemistry (IUPAC).
There were around 52 known elements in the periodic table in 1834. The periodic table was still in its early stages of development during this time, and many elements were discovered and added to the table in the years that followed.
It took about 160 years after Robert Boyle's time for scientists to formulate the periodic table of elements. The periodic table was created by Dmitri Mendeleev in 1869, building on the work of many other chemists who contributed to our understanding of elements and their properties in the intervening years.

Many modifications were done. Finally moseley's periodic table was accepted.
it toke 2 years

the oldest known element in periodic table is copper -8000 years old know element thank you
it is what scientists used to use years and years and years and years and years ago.
Please, don't be ridiculous ! Chemistry is a science, the periodic table has a history of approx. 150 years; any link with any conspiration theory.
Radon is a noble gas (non-metal) in the periodic table so it appears in the atmosphere as radioactive gas with a quantity of about 0.01%. the standard state of Radon is gas in atmosphere so it is placed in periodic table as gas...the gas exist since billion of years and history of periodic table is thousands of years....
