Lanthanoids and actinoids are placed in separate rows in the Periodic Table primarily due to differences in their electronic configurations and their chemical properties. The lanthanoids, which include elements 57 through 71, primarily fill the 4f subshell, while the actinoids, elements 89 through 103, fill the 5f subshell. This distinction reflects their different behaviors and reactivity, with actinoids often exhibiting more complex chemistry due to their ability to exist in multiple oxidation states. Additionally, separating them helps maintain the table's structure and readability.
What else can I help you with?
Rows on a periodic table?
7 + 2 for the lanthanoids and actinoids.
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 are the lanthanides and actinides found on the periodic table?
They are found below the periodic table because they would take up too much room in the periodic table
Why are there two rows of elements below the periodic table?
The two rows below the main periodic table are the lanthanides and actinides. These elements are placed separately to prevent the table from becoming too wide. Lanthanides start at atomic number 57, while actinides start at atomic number 89.
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 is special about the two rows directly below the periodic table?
The special thing about the two rows directly below the periodic table is that they are lanthanoids and actinoids. They are both highly reactive with halogens and chalcogens. Actinoids react more easily, however.

John placed 128 beads in equal rows his friend has 125 beads it is possible for them to have the same number of beads in a row explain?
No because you can't put into even rows

Where in the periodic table would one find the inner transition?
At the very bottom -- those 2 separate rows are inner trans.
What was Dmitri medeleevs contribution to the periodic tale?
Mendeleev arranged the elements in order of increasing atomic mass.He placed the elements in rows and columns.
Why do you need to be able to split a window in Excel?
It can be very useful for looking at completely separate parts of a large worksheet. So you could be able to look at some rows near the top in one of the split windows and be looking at some rows that could be hundreds of rows down in another part. You may want to do it to compare things or check some details or formulas. You don't need to scroll up and down to the two separate sections if you can split the window.
