Na- is the largest, because when total electrons are equal then,

Size is inversely proportional to charge.
Since -1 is the least charge hence has maximum size.

TRR: Its highly impossible to form Na- ion I think.
Debdipta: why
TRR: Na cannot gain 1 electron.
TRR: It should lose 1 electron to gain octet confg.
07161020: its just an assumption
Debdipta: it has one unpaired s orbital
