#3. Part B Rank the following items in order of decreasing radius: Ca, Ca2+, and Ca2−. Rank from largest to smallest radius. Part C The following ions contain the same number of electrons. Rank them in order of decreasing ionic radii. Rank from largest to smallest radius. To rank items as equivalent, overlap them.
|Rb+, Br-, Sr^2+, As^3+, Se^2-, Y^3+|
AnswerPart B Ca-2 > Ca > Ca+2 Part C Note : in place of As3+ it should be As-3
As-3>Se-2 > Br – > Rb+ > Sr+2 > Y+3
