The Periodic Table of elements is a chart that organizes the elements and emphasizes their shared traits and commonalities. All the known elements and their atomic number are on the periodic table.
The Lanthanides and the Actinides have been moved in the periodic table simply to save space.

The Lanthanides and the Actinides,
They are only there to save space.
The are Actinoids and radioactive metals but mostly are synthetic.
The elements are the lanthanoids and actinoids.
The last row comprises the actinides.
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
After lanthanum, thus the name.
Atoms to the left on the periodic table Atoms with a large atomic radius
The elements with similar properties are placed in groups. Periodic table contain 18 groups.
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
The f-block elements are placed at the bottom of the periodic table because if they were placed where they belong the periodic table would be too big to fit on a normal sheet of paper.
The elements that are placed outside of the periodic table are called transactinides. These elements are usually placed in a separate row below the main table and are synthetic elements that do not occur naturally on Earth.
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
they are the lanthanide and actinide series of rare earths
At the bottom of the Periodic Table
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
Metals are placed at the left. Non-metals are placed at right in periodic table.
The periodic table is an array of various elements. Iodine is an element. Hence it finds it place on the periodic table.
The periodic table contain all chemical elements, placed in a rational order.
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
All chemical elements are placed in the periodic table.
After lanthanum, thus the name.
