As a start, try writing them as the "lanthanides". This group consists of the fifteen elements from lanthanum, with atomic number 57, through and including lutetium, with atomic number 71. In most periodic tables, they are in a separate row at the bottom of the table, often with a footnote reference at the spot on the table between barium and hafnium.

Platinum has a relative atomic weight of 195.09(you will not find 5.09 anywhere else on a periodic table.)

Not true I am trying to find the same thing out but I no for a fact they are both on a periodic table.
The periodic table doesn't show grams; and which grams ?

No
I can find only two types The Mendeleves Periodic table based on Atomic weight of elements and The Modern Periodic table based on Atomic number of elements.
you find the ones that have been added to the periodic table in the old days

The physical properties are not listed in periodic table. The properties like density is not listed.These can't be found on periodic table.
