							All have 3 shells but number of electrons are lowest in Na element so Na has largest atomic radius because increasing of electron (only when shells remain same) increases nucleus attraction.OR in periodic table atomic radius decreses on going left to right thus given elements are in 3 period and Na is the first element on going left to right in period.Na>Al>Si>Cl
