because they have different opinions about each other
I think there should be different forms of periodic table because there is a lot of elements that is not yet discovered.
The scientist who recognized the periodic table for atomic number was Henry Moseley. He discovered that elements should be ordered by atomic number rather than atomic mass, which led to the modern understanding of the periodic table.
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.
Marriages should be arranged if the two people involved want them to be.
the periodic table of elements is arranged by what?
they should reason with each other until they have a good or decent answer to their problem.
No there should not be arranged marriages. People should have choices in whom they want to spend the rest of their lives with.
Scientists should consider using universal pH indicator because it can provide a wide range of colors to indicate different pH levels.

He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than atomic mass.
The Periodic Table lists all the elements. In the 1860s Dmitrii Mendeleev organised the elements into a table leaving gaps where he thought elements should be. The modern periodic table is maintained by an organisation called IUPAC, International Union of Pure and Applied Chemists.
Well some are metals and non-metals ( Which you should know dat ) and each has a different meaning.. To us. GabrielAk-47boy
