The Halogens Family

            
             The Halogen family is the vertical group of elements labeled as 7A on the Periodic Table. The elements in the Halogen family are nonmetals. They are also the most reactive group of elements on the Periodic Table. The elements found in the Halogen family are: Fluorine, Chlorine, Bromine, Iodine, and Astatine. They are the most reactive because they have seven electrons in there valence shell. For them to become stable they need eight, so they react very easily. Fluorine, the element located highest in the Halogen family, is the most reactive element on the Periodic Table. The greatness in reaction goes from the bottom to the top in the Halogen Family, where the top is the highest.
             In this experiment you will observe reactions of the Halogen family, and verify reactions of them.
             Purpose: Find similarities between all the elements in the Halogen family and which element is the most reactive.
             Materials:.
             test tubes, 13x100-mm(4) pipet dropper.
             test tube rack safety glasses.
             1 M solutions of: Hexanes.
             NaF 3.0M NH3(aq).
             NaCl chlorine water.
             NaBr .
             NaI.
             Ca(NO3)2.
             AgNO3.
             Procedure:.
             Part I.
             1. Put 4 test tubes in test tube rack.
             2. Add a different solution to each tube: NaF, NaCl, NaBr, NaI.
             3. Add Ca(NO3)2 to each solution.
             4. Then observe and record observations.
             5. Clean test tubes.
             6. Repeat but instead of adding Ca(NO3)2, add AgNO3 to each solution.
             Part II.
             7. Add NaI, NaBr, NaF to 3 test tubes.
             8. Add hexanes to those solutions and observe.
             9. Then add chlorine water.
             10. Record your observations.
             Observations and Data:.
             Part I.
             2. NaF + Ca(NO3)2: Cloudy color.
             NaCl + Ca(NO3)2: NR.
             NaBr + Ca(NO3)2:NR.
             NaI + Ca(NO3)2:NR.
             3. NaF + AgNO3: NR.
             NaCl + AgNO3:Milky white has little chunks.
             NaBr + AgNO3:yellowish white.
             NaI + AgNO3:green has little chunks.
             4. NaCl turned clear and lost its chunks.
             NaI is milky green and has chunks.
             Part II.
             5. No Reactions.
             There are two layers in all solutions.
