For each unknown element shown in the video, describe its appearance in the table below. A conductivity probe will be placed on each sample. The brighter the light, the more conductive.
Record your observations in the table below
An iron ring will be used to hit each sample to test it's malleability. Record your observations in
the table.
A small sample of each element will be placed in a test tube. A few drops of HCI (hydrochloric
acid) will be placed in the test tube with the sample. If you see a chemical reaction taking place,
indicate what evidence you have to support that observation below. If no reaction is observed,
indicate that in the table as well
6. A small sample of each element will be placed in a new clean test tube. A few drops of Cuci
(copper Il chloride) will be placed in the test tube with the sample. If you see a chemical reaction
taking place, indicate what evidence you have to support that observation below. If no reaction is
observed, indicate that in the table as well.
