Mendeleev used the increasing atomic mass of elements to arrange them in rows on the periodic table. This allowed for elements with similar properties to be grouped together and for the gaps to be left for undiscovered elements.
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.
The element to the left of copper on the periodic table is nickel. Nickel has the atomic number 28, while copper has the atomic number 29.
