A Periodic table The Periodic Table of the Elements.
Out of the first 18 elements on the periodic table, 10 are solid
There are a total of 118 elements known to exist on the periodic table.
Radioactive elements exist in all groups of the periodic table.
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
First of all it is a compound made of different elements, hence it cannot exist in periodic table. Periodic table is composed only of pure elements not in any combined form.
