Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
There are far to many elements following the 6th on in the Periodic Table. Included below is a link to a very nice Periodic table.
Non-metals are located on the very right of the Periodic Table. Metals are on the left.
Dmitri Mendeleev, a Russian scientist, is credited with creating the periodic table of elements in the 19th century. He arranged the elements in order of increasing atomic mass and grouped them based on their chemical properties, leading to the development of the modern periodic table.
Mercury is considered a weak metal on the periodic table. It is a liquid metal at room temperature and has a low tensile strength compared to other metals.
The periodic table is very useful.
Yes, there were elements on the first periodic table. I believe that there are still elements on the periodic table.
Periods are horizontal.Groups are vertical.Just think group = up and downperiod= right and left
Hydrogen is found at the very top left of the periodic table. It is the first element on the periodic table and it is shown with the atomic symbol H.
on the very right side of the periodic table. (the farthest column to the right)
Moseley
about 106 are on a periodic table for the very time being
From the very beginning.
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
The very last row on the right
He- helium it is a noble gas (very unreactive)
H on the periodic table represents Hydrogen. This is the lightest element but it is very essential to life because it is a major component to water (H2O).
