Arrange these elements in order of decreasing atomic size: sulfur, chlorine, aluminum, and sodium. does your arrangement demonstrate a periodic trend or a group trend

Arranging the given  elements in order of decreasing atomic sizes ;

The arrangement of elements based on Atomic numbers is a periodic trend ( because elements are categorized/ put in different patterns  in the periodic table based on their atomic sizes ).  while

A group trend groups elements in vertical order based on their characteristics and not atomic size.

Hence we can conclude that Arranging the various elements in order of decreasing atomic sizes is ; Sodium > Aluminum > Sulfur > Chlorine
