Smallest atom is hydrogen
Largest atom is Francium
group 1
The largest atom is francium and has 87 protons and 87 electrons.
The smallest element known to man is Hydrogen (H).
1s2,2s2,2p6,3s2,3p2 (Si)
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.

A atom is not on the periodic table, atoms are inside the elements and compounds on the periodic table if this helps :)

Fluorine because it has a smaller atomic radius.

A period 8 don't exist now in the periodic table of Mendeleev.
