Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
Where does neptunium fit on the periodic table?
Neptunium is a member of the actinides group.
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.
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 (:

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
