The atomic size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.
The atomic radius decreases.
Examples for the groups I an II of the periodic table:- the atomic radius grows from top to bottom- the electronegativity descends from top to bottom
atomic radius decreases from bottom to top of the periodic table.
The atomic radius decreases.
As you move from the bottom to the top of the periodic table, the atomic size decreases. This is because the number of protons in the nucleus increases, leading to a stronger pull on the electrons. Electrons are added to the same energy level while moving up the table, resulting in a smaller atomic radius.

Actinides comprise of atomic number 90-103. They are placed at bottom of periodic table.

Towards the bottom, atomic mass increases. Atomic number also increases.
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
The number of protons in the nucleus of an atom, which is the atomic number, determines the order of the periodic table. Atoms are arranged in increasing atomic number from left to right and top to bottom in the periodic table.
