Idk
I don’t know
See the link below fot the IUPAC model of the periodic table of elements.

WRONG!!!! Sulphur is NOT a metal. Elemental sulphur is a non-metal.
The short answer: No. There is, as of yet, no 119th element. A lot of people say that the Periodic Table is full and there are no others left, but based on history everyone who has ever said that has been proven wrong. Only time will tell.
The only important difference is that the modern periodic law must be framed in terms of atomic numbers, where Mendeleev framed the original periodic law in terms of atomic weights. There are only three places where this makes a difference. For cobalt and nickel Mendeleev assigned both exactly the same atomic weight -- well within the error margins at the time. For tellurium and iodine, Mendeleev insisted, wrongly, that the recognised atomic weight of tellurium was wrong, and that it had to be less than that of iodine. And the third case did not come up until later, because argon was not discovered until 1894 (element number 18, argon, has an atomic weight greater than that of element 19, potassium).
it wasn't a real table

Because it is not this xeon is not the only gas in the periodic table beginning with X. That is wrong can someone correct this please
Sorry if I'm wrong but it is it in transition metals
the Greeks thought it was air, water, earth and fire but they were wrong
No,its not Dmitri Mendeleev.Dmitri Mendeleev create the first periodic table but mostly it was wrong....he arranged them by the atomic number when it should have been by increasing the atomic number(and ya there's a difference)..the one that rearranged it was Henry Moseley.
Thallium Wrong, check the periodic table, it's "Thorium" number 90 on the table
Aluminium (in the US it is known as "Aluminum" but this is just plain wrong)
Actually in response to this answer, everything I have read clearly states that metals far out number all nonmetals, just look at the Periodic Table. that guy is so wrong you are right :) SO HELP FULLU JERK WE HATE U >:< Your answer is correct I have checked it this answer has been given a certified stamp by: Gabriel
When it was discovered that Mendeleev's table was based on the wrong characteristic. He believed that it was the mass of the elements that affected their properties. It is, in fact, their atomic numbers
Hydrogen
As of July 2009, there are 117 elements on the Periodic Table.As of November 2009, there are 126 elements on the Periodic Table.3 are recently discovered and don't have much data, unless my previous number wer counted wrong. Hope this helps!
