Because the elements classified as actinides and lanthanides share many of the qualities that elements in the same period (malleability, reactivity, hue, etc.).

Why are two of the rows of the periodic table deprecated from the rest of the chart?
There are two rows deprecated from periodic table because they have different properties.They are referred as lanthanides and actinides
Why are the two bottom rows of the periodic table not attached to the rest of the table?
because they are less important metals
What are the two rows at the bottom of the periodic table there?
The name of bottom two rows of the periodic table is lanthinedes and actinides.
Vertical column on periodic table?
the answer is groups.Added:There are 18 main groups and two special ones (with 14 lanthanides and 14 actinides respectively).Groups contain elements with the same 'outer' electron configuration (valence electrons).Note: Vertical rows are actually called: columns
Which periods of the periodic table contain trans ition elements?
All the transition elements are metals. In the usual wide form periodic table, the transition elements are in columns 3 - 12 and in two rows at the bottom of the main table. Those in the rows at the bottom are also called "inner transition elements".
What are the two names for horizontal rows on the periodic table?
The two names for horizontal rows on the periodic table are periods and series.
Why are two of the rows of the periodic table deprecated from the rest of the chart?
There are two rows deprecated from periodic table because they have different properties.They are referred as lanthanides and actinides
Where are lanthanides on the periodic table?
Top row, of the bottom two rows on the Periodic Table. (Period 6, starting at group 4)
What are the rows named in the periodic table?
Rows are known as periods. They exist as horizontal lines. The bottom two rows are lanthanides and actinides.
Why are the two rows at the bottom of the periodic table separated?
because they are of f group
How many periodic are there in modern periodic table?
In the periodic table of the elements there are 7 periods and 18 groups. The rows are called periods and columns are called groups. You may be getting confused by the lanthanides and actinides. These groups of elements are found in two rows at the bottom and seem to not be a part of the table. However, if you find and extended version of the table you will see that, technically, these two rows belong in Periods 6 and 7.
Why are the two bottom rows of the periodic table not attached to the rest of the table?
because they are less important metals
Why are two rows at the very bottom of the periodic table not placed within rows 6 and 7 where they belong?
it just makes the table too long, the version where they are not taken out is called the extended version, you can look it up, when you see it it is pretty obvious why they would condense the table in that way.
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.
Where is the f region of the periodic table?
The two rows of elements placed below the periodic table are known as f block elements. The two rows are also known as lanthanides and actinides. In these elements, the electrons are filled in the antepenaltimate f orbital.
Why are there two rows of elements below the periodic table?
This is so, because these rows separate f-block of the elements from other blocks.
How are the elemeents in the rows of the periodic table similar to the elements in the columns?
As in any two dimensioned table (Rows and Colomns) each particular element1) is in one 'Cell' at the croccing of R's and C's. 1) An element can be 'chemical' in the periodic table or 'numerical' in a calculus table, or mixed in an accounts table
