Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
What is the bottom section of the periodic table for?
The bottom section of the periodic table is for the lanthanides and actinides, which are also known as the inner transition metals. These elements are placed below the main body of the periodic table to keep it compact, as they would otherwise disrupt the table's organization.
What is the section of elements that are placed outside of the periodic table called?
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.
What group is astatine in the periodic table?
Astatine is placed in group-17 in the Periodic Table. Its symbol is At.
Why are lanthanoids and actinoids placed at the bottom of the table?
Because their electronic configuration is ended at 'f' orbitals and can not be placed in 's','p' and 'd' blocks.
WHAT IS FE2O3 IN PERIODIC TABLE?
Compounds are not placed in the periodic table.
Where are there actnoides placed on the periodic table?
Actinoids are placed in a separate row under the periodic table.
When new elements are placed into the periodic table what happens?
If new elements are placed, then they would be appended in the periodic table. It won't disturb existing periodic table.
