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.
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.
Where do lanthanids and actinides fit into the periodic table?
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.
Where are the lanthanides and actinides placed on the periodic table?
At the bottom of the Periodic Table
What are the two rows of metals that appear at the bottom of the periodic table?
elements 56 through 71 are called the lanthanoids
What is placed at the bottom of the periodic table because they are too wide to represent the chart form?
f-block elements (lanthanides and actinides)
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.

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.
Where do lanthanids and actinides fit into the periodic table?
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.
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
Which elements in the periodic table are by the place?
Metals are placed at the left. Non-metals are placed at right in periodic table.
Elements in a periodic table in common?
The periodic table contain all chemical elements, placed in a rational order.
