The name of bottom two rows of the periodic table is lanthinedes and actinides.
The table would be to large if it was with the table it belongs in the 6 and 7 period and goes between lanthanum , actinium and hafnium, rutherfordium
Lanthanide and Actinides solids and synthetics
Elements 56 to 71 are called the lanthanide series and elements 89 to 103 are called the actinide series.
The two rows at the bottom of the Periodic Table are called the Inner Transition elements
The two names of the rows that are below the main part of the peridoc table are Lanthanide Series, & the Actinide Series. (:

because they are less important metals
There are two rows deprecated from periodic table because they have different properties.They are referred as lanthanides and actinides
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".
The Periodic Table has 7 periods (horizontal rows) and 18 groups. The two groups of 14 elements at the bottom (lanthanides and actinides) are parts of the 6th and 7th periods, between groups 2 and 3, but are placed below to limit the displayed width of the table.
Because the elements classified as actinides and lanthanides share many of the qualities that elements in the same period (malleability, reactivity, hue, etc.).
Top row, of the bottom two rows on the Periodic Table. (Period 6, starting at group 4)
because they are of f group
because they are less important metals
Rows are known as periods. They exist as horizontal lines. The bottom two rows are lanthanides and actinides.
elements 56 through 71 are called the lanthanoids
The two names for horizontal rows on the periodic table are periods and series.
At the bottom of the Periodic Table
Two rows of elements called the "LANTHANIDES" and the "ACTINIDES".
Periods and the vertical columns are groups
The bottom two rows of Lanthanide & Actinide is the transition metals
The f-block elements (lanthanides and actinides, the two rows at the bottom of the periodic table) are known as inner transition elements
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.
