Lab Report - Metal or Non- Metal

Abstract: During this lab Jilly Abby and I were checking to see if unknown elements were metals, non - metals or metalloids, by there apperaence, conductivity, durability, and reactivity. An example of a metal in everyday life are copper and silver coins. Realizing how important metals are made me really excited for the lab.


Procdure:

While testing to see weather the elements were metals or non- metals, Jilly, Abby and I first placed each of the elements in a well plate and labeled the unknown substances with numbers.

Before starting the actual prosedure, we examined the physical appearence of each substence for there color, texture, form, luser and recorded the information.

Next, we individually tested the conductivity of each sample, and recorded the results for each one.

We then tested the durability for each of them, by gently hitting them with a hammer. We then recorded whether the substance was malleable or brittle.

After testing the durabillity of the samples, we placed them back into the well plate and poured 15 - 20 drops of 0.1 M copper (II) chloride (CuCl2) to each sample. We timed the the 0.1 M copper (II) chloride (CuCl2) for about 4 min. and observed drastic changes in some of the elements. Element 7  had changed from a blueish color to black. After we finished with the 0.1 M copper (II) chloride (CuCl2) we disgaurded the well plate.

Carefully, we then used the dangerous acid and dropped about 15 - 20 drops to each sample. While timing the acid for about 4 min. we observed changes in the substances. Sample 7 started to reacted with the hydrochloric acid to form  bubbles.

Lastly, we disgaurded the contents in the well plate.


Results:
unknown substence a tested as a metal
element b tested as a metaloid
