What else can I help you with?
Why are the lanthanides and sctinides placed at the bottom of 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.
Which chemicals are placed at the bottom of the periodic table?
Actinides
Were are the lanthanides placed on the periodic table?
The lanthanides are a series of elements that are placed at the bottom of the periodic table. They are located in the f-block, specifically in the period below the main body of the periodic table. The lanthanides have atomic numbers 57-71.
Where are the antinides on the periodic table?
Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.
The two rows of elements placed at the bottom of the periodic table represent what elements?
The two rows of elements at the bottom of the periodic table are the lanthanides and actinides. The lanthanides are elements with atomic numbers 57 to 71, while the actinides are elements with atomic numbers 89 to 103. These rows are known as the f-block elements and are placed below the main body of the periodic table to conserve space.
What are the two rows of metals that appear at the bottom of the periodic table?
The two rows of metals that appear at the bottom of the periodic table are the lanthanides and actinides. They are known as the inner transition metals and are placed below the main body of the periodic table to keep the table size manageable.
What do the gaps on the periodic table represent?
The gaps represented the elements which were not discovered. When the elements were invented, they were placed into these gaps.
Why are lanthandies placed below the periodic table?
Lanthanides and actinides are placed below the periodic table because of their unique physical and chemical properties.
Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
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 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.
