Give the symbol of the element that has the (3.8)a.

Solution 113CQStep 1 of 5a.Here, we have to find the smallest atomic size in the group 6A (16).6A (16) group elements:6A group elements are commonly called as Oxygen family.6 A group elements are Oxygen(O), Sulfur(S), Selenium(Se), Tellurium(Te), Polonium(Po).They have six electrons in their valence subshells.Except Oxygen all these elements are solids at room temperature. Atomic size:It is the average distance between a nucleus and outermost electron.As you move down the group in the periodic table the atomic size increases.Therefore, smallest element in the smallest atomic size in the group 6A (16) is Oxygen.______________________________________________________________________________
