Will the periodic table always look this way?
In more than 150 years the periodic table had many versions; hundred versions of this table are known. The sole official table is today the IUPAC Periodic Table.
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.
What ways was Mendeleev's periodic table inaccurate compared to the modern periodic table?
Many more elements are known today then when Mendeleev laid out his table. In addition, he arranged his table by atomic mass and there are places in the periodic table where mass does not always increase. An example is between tellurium and iodine.
What does In in the periodic table stand for?
periodic table stands for all the elments scientist have found till today. Example: gold, silver, oxegon, carbon dioxide,ect.
Who was the scientist responsible for the first periodic table?
To study elements many attempts were made to classify the elements.Dobereighner tried to arrange the elements int groups of three and called them as Dobereighner' triads.Newland also categorized the elements in groups of eight like the musical notesand called them Newland's octaves.But the most credited person for creation of periodic table was Dimitry Ivanovich Mendeleev who arranged the elements on the basis of increasing atomic massesand made an actual periodic table placing all the discovered elements discovered at that time. Not only that, he also left spaces for future elements to be discovered.But there were some defects in his table which were corrected by Henry Mosleywhen he formed the modern periodic table based on increasing atomic number.
Who uses the periodic table today?
Chemists

How does the periodic table relate to anything going on in the world today?
well every known materialthat we asociate with is listed in the periodic table.
What is a group of elements in the periodic table?
A group is a column in the periodic table of elements.
Who rearrange the periodic table by atomic number into the table you recognize today?
Henry Moseley
Who is the inventor of the periodic table you use today?
Dmitri Mendeleev.
How many chemical element do you have in your periodic table?
Today (June 2013) the periodic table contain 118 chemical elements, natural or artificial.
What did Dmitri Mendeleev discover?
he drew up a table that grouped elements according to their atomic weights, his table became the basis for the periodic table of elements used today.
Who made the periodic table used today?
Henry Moseley in 1914
Is the periodic table completely finished today Why or why not?
No there are still undiscovered elements
How does mendeleevs periodic table differ from moselys periodic table?
Mendeleev's Periodic Table was different from Moseley's in that Mendeleev arranged the elements inÊthe table according to atomic masses while Mosley's periodic table was arranged accordingÊto atomic numbers that were increasing.ÊÊThe modern periodic table used today is based on the Moseley model.
