Metal, Nonmetal, Metalloid Lab

Hey you guys, sorry I am putting this up a little late!

Today's class period was spent doing the metal, nonmetal, and metalloid lab. If you were absent on Friday when we got the lab you can get it here.

In this lab we tested 8 elements; aluminum (Al), carbon (C), Iron (Fe), Magnesium (Mg), silicon (Si), Sulfur (S), tin (Sn) and zinc (Zn) for 4 psychical properties and their chemical property.



For Each of these 8 elements we looked at their appearance and looked for luster(if they were shinny or dull). We also tested for their malleability. Which means when we hammered them, were they flat or did they break. And last we tested for their electrical conductivity.


What you see here is the malleability test being conducted.


This is the object we used to see (well actually hear) the electriacl conductivity. (If anyone has any cards with sound in them, you can brign them in to Mr. Lieberman)

After looking at the physical properties were tested their chemical properties by taking a little bit of each of the elements and putting them into 2 test tube. Then we add hydrochloric acid to one test tube and observed the changes and to the other test tube we add copper chloride and also observed the changes and made note of these in our data table.

Your homework for tonight is to work on the lab which is due on Wednesday, to do the webassign for tomorrow and to do the chemthink which is due next Monday.

That was all for today!
and the next scribe is.................. Rachel K. Good Luck!
