Lanthanides (elements with atomic number 57-71) and actinides (elements with atomic number 89 to 103) are placed at the bottom of the Periodic Table.
What else can I help you with?
Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
How does silver fit in the periodic table?
Silver is the 47th element on the periodic table. It is located in period 5 and group 11 in the periodic table.
Where does neptunium fit on the periodic table?
Neptunium is a radioactive actinide element with the atomic number 93. It is situated in the actinide series of the periodic table, which is the row below the lanthanide series, between uranium and plutonium.
Who is shown at the bottom of the periodic table just to keep it at a reasonable size?
Two rows of elements called the "LANTHANIDES" and the "ACTINIDES".
Why do elements appear more than once in the periodic table?
The modern periodic table doesn't, but someone probably organized the periodic table by characteristics. A few elements have multiple characteristics of various groups or periods.... Ergo, it would be fitting to place an element in multiple spots of the table as seen fit. Hope this helps (:

Why are the actinides and lanthanides at the bottom of the table?
Just so it can fit on one page

Where and why does platinum fit in the periodic table of elements?
Pt and an atomic number of 78
How would you predict where it would fit in the periodic table if you did not know it's atomic number?
I'm assuming you have the internet because you used this website. look up an online periodic table and find the element you need on the table
Why are two of the row of the periodic table separated from the rest of the chart?
Oh honey, those two rows at the bottom of the periodic table are like the misfits at the cool kids' table. They're separated because they're the f-block elements, also known as the lanthanides and actinides. They're down there minding their own business, doing their own thing, and adding a little extra spice to the periodic table.
