PLEASE ANSWER ILL GIVE BRAINLIEST AND 20 POINTS
Refine/Expand the Experiment
Assume you expand the group of materials you have to test to include metals. The
forces that hold the atoms together in a metallic solid, or piece of metal, are referred
to collectively as the “electron sea." This is because, in a metallic solid, electrons do
not stay close to a single atom, rather they move through the metal quite readily. The
resulting electrostatic force between the positive nuclei of the metal atoms and the
negative electrons is very strong and keeps the metal in the solid state. Given this
information, describe the results you would expect to observe if you performed the
melting point and conductivity tests on a metal sample.
