Atoms size get smaller as you go across from left to the right in periods and gets larger down the group on the periodic table.
For a given group, the largest atom is in period 7. For a given period, the largest atom is in group 1.
Heaviest
The largest (heaviest) NATURAL element is uranium, number 92. (Natural plutonium is extraordinarily rare.)
The largest (heaviest) elements are the synthesized radioactive elements in row 7, atomic numbers 104 to 118. The heaviest atom of a named element is 293Lv (livermorium-293). The heaviest possibly observed are ununpentium-294 and ununoctium-294.
Largest Atomic Radius
The element cesium (caesium, Cs), atomic number 55, has the largest atomic radius in period 6. Only francium(row 7) may be larger, but testing is difficult because francium does not exist in any meaningful amounts (maybe 30 g on the entire Earth).
The largest atom (in terms of volume not Atomic Mass or weight)
lithium or boron
Cesium (Cs), in the lower left hand corner of the table, has the largest known atom
The lower part contains the larger atoms. the atomic size increases down a group. It decreases from left to right of a period.
Francium has the greatest atomic radius.
Francium has the greatest atomic radius.

The periodic table contain neutral atoms not a list of cations; most metals are to right.A cation is an atom who lost electrons.
there is no one answer to this question. It all depends on where the atom is in the Periodic Table.
Most of the elements on the periodic table are metals.
The most corrosive elements on the Periodic Table are all of the halogens.
The most reactive nonmetals are the halogens in group 17 of the periodic table.

I think it is Ununoctium.
Any atom in the first family of the periodic table of elements is very unstable.

Carbon is the smallest atom having tetravalency. Note that carbon is the atom in the uppermost* period of a wide form periodic table that includes column 14, the column in which the most common valency is tetravalency, and in general atomic size is greater the lower in a periodic table that the atom appears.___________________________*This is the second period of the table as a whole; the first period includes only columns 1 and 18.
in the Periodic Table it is the most reactive metals!
Most of them are metals.
