Rank the following items in order of decreasing radius: ca. ca2+. and ca2−.

#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+

Answer

Part 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
