There are three electronic shells in sodium while four in iron so Iron is larger in size. other words to make it shorter it would be the iron
No. A cesium atom is larger both in terms of atomic mass and atomic radius.
No difference. Invoking "element" simply refers to chemcial properties, and these are present in the atom as well.
An iron atom is a different element than a sodium atom because it has a different ground state electron configuration. In fact, any atom that differs from any other atom in ground state electron configuration is a different element.
It becomes an ion with a larger radius than the atom of chlorine
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.

the sodium atom as it has a larger nucleus and more electrons.

Yes. Sodium has 12 neutrons whereas iron has 30 neutrons for their most stable isotpe.

The sodium atom is much bigger than a sodium cation with a plus 1 charge, because the "lost" electron of the ion had a higher principal quantum number than any remaining electron in the ion and therefore was distributed through a larger volume of space than any of the remaining electrons.
yes sodiom atom is an isolated one it is the atom of sodium sodium chloride is salt
An iron atom is the smallest iron particle that still has the properties of iron.
a larger nuclear charge
No. It is an element. Although you can have one atom of sodium.
