What completed the periodic table?
The periodic table cannot be said to be completed. New elements (admittedly radioactive and short-lived), are still being made.
Will the periodic table always look the same?
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.
How does the periodic table effect the modern world?
because if you find out what a periodic table is and go on a different website you can find it out but everyone wanted to see what is was so if you need more information go on a different website.
Who recognized a pattern in the properties of the elements and made the first periodic table?
In 1869, a Russian scientist named Dmitri Mendeleev arranged the elements in a table according to their atomic mass, this was the first periodic table. However, a few elements didn't fit the pattern in Mendeleev's table, so a new table had to be made, and that table is today's periodic table which is arranged by atomic number, and not atomic mass.
What are the most metals on the periodic table?
There are 91 metals in the periodic table today, but new ones are added as time passes.
When new elements are placed into the periodic table what happens?
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
How many periodic tables have there been?
Mendeleev's created the periodic table in 1869 since then it has been as new discoveries have been made
What changes were made to the periodic table after Dmitri mendeleevs discovery?
they changed the 3 new Elements.

Who introduced new periodic table?
Women
What is the difference between the new and old periodic table?
Well, Back when Medeleev made this table, many of the elements were not even discovered yet. He plotted only the elements that he knew on his table. He organized them by increasing atomic weight. He didn't know all the elements so he would put question marks and empty spaces in the spots he thought elements would be and left to be found by other scientist. He happened to be true about the missing elements and that scientist did end up finding these "missing links" of the periodic table and led to the new or modern periodic table. The modern periodic table doesnt have any missing elements and they changed Medeleev's way of organizing the table by increasing atomic weight to increasing atomic number. So the newer form of the periodic table was complete and made it easier to find what elements react better with other elements. This making the modern table became the more efficent table of our time.

What is a group of elements in the periodic table?
A group is a column in the periodic table of elements.

When did mendeleev create a new row in his periodic table?
Mendeleev supposed that a new row is necessary in the periodic table after the discovery of lanthanoides.
