Advance Study Assignment: The Alkaline Earths and the Halogens 1. All of the common noble gases are monatomic and low-boiling. Their boiling points in C are: Ne,-245; Ar, -186; Kr, -152; Xe, -107. Using the Periodic Table, predict as best you can the molecular formula and boiling point of radon, Rn, the only radioactive element in this family. 2. Substances A, B, and Ccan all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A", B, and C ions, all of which are col- orless. When a solution of A is mixed with one containing Cions, the color changes from green to red. Which species is oxidized? Which is reduced? When a solution of A is mixed with one containing B ions, the color remains green. Is A a better oxidizing agent than B? Is A a better oxidizing agent than C? Arrange A, B, and C in order of increasing strengths as oxidizing agents. 3. You are given an unknown, colorless, solution that may contain only one salt from the following set: NaA, NaB, NaC. In solution each salt dissociates completely into the Na ion and the anion A, B-, or C, whose properties are given in Problem 2. The Nat ion is effectively inert. Given the availability of solutions of A, B, and C, develop a simple procedure for identifying the salt that is present in your unknown

Explanation / Answer

Ans 1 :

As the general trend is observed for the boiling points in the noble gas group that boiling point is increasing down the group with similar intervals.

So the boiling point of Radon will be more than the Xenon , it will be approximately -62oC.

The chemical symbol of radon is Rn.

Rn ; -62oC
