D block elements are at the center of the Periodic Table; f block elements are at the bottom.
Lanthanum is located on the right to the bottom side on the periodic table.
At the bottom of the Periodic Table
From the bottom to the top, the elements of the atomic periodic table have less mass and are more stable, in general.
The elements with the highest mass are on the bottom right of the periodic table.
In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
On left side and center of the periodic table.
Metalliods are found at the center of the periodic table.
After lanthanum, thus the name.
Lanthanum is located on the right to the bottom side on the periodic table.
There are four blocks named as s, p ,d and f.
The transition metals are found toward the middle of the periodic table.
the energy level increases as we move from top to bottom in the periodic table
At the bottom of the Periodic Table
The three families that are found in the center portion of the periodic table are the Iron group, the Cobalt group and the nickel group. There are 18 families in the periodic table.
From the bottom to the top, the elements of the atomic periodic table have less mass and are more stable, in general.
Because their electronic configuration is ended at 'f' orbitals and can not be placed in 's','p' and 'd' blocks.
There are total 18 groups in the periodic table that contains elements having same properties.
