Elements of the Periodic Table
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Yes, it has the atomic # of 20 on the periodic table of elements.
Elements are found on periodic table. Compounds are not present on periodic table. The table does not contains mixture.Elements can be found on a periodic table. Compounds can be made by bonding two or more elements. But they are not depicted on the periodic table.
periodic table is an arrangement of elements. Thiamin is not an element and hence not on the periodic table.
That stands for "One hundred eight Elements in the Periodic Table", but this is now obsolete. As of 2008, at least 117 elements have been discovered.
