Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. Therefore, Clis the only gaseous element has the greatest density at STP.
Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.
Mathematically,
Density = Mass of the element ÷volume marked on the graduated cylinder
From formula we can see that density is directly proportional to molar mass of the given element. the increasing order of molar mass is N< O<F<Cl. The increasing order of density would be N< O<F<Cl.
Therefore, Cl is the only gaseous element has the greatest density at STP.
