Metal, Nonmetal, Metalloid Lab

Post by: Kevin M
Date: 9/16/13

Today we started class by turning in our Beverage Density Lab. Ms. Friedmann then passed back our Unit 1 tests that we took on Thursday. The test was out of 80 points. The class did great by averaging 90% on the multiple choice section. If this impacts your grade negatively, don't worry! It is the first test and has a big impact on our grades at the moment but can easily be raised by the next test.


The Lab: The purpose of this lab is to investigate the physical and chemical properties of eight elements and to classify the elements as metals, nonmetals, or metalloids. 

     Prelab Answers:  1) Hydrochloric acid is corrosive to skin and eyes. Copper Chloride is toxic. Although these samples probably won't be a problem, protect youself. Hydrochloric acid could burn but most likely won't. The best defense against damage is to be careful and use the skills we learned in the beginning of the year. After the lab you should definitely wash your hands to be sure. If your skin was contacted, it would take a couple of minutes to visibly appear.

     2) Al- Aluminum- Marked as A
         C  - Carbon- Marked as B
         Fe- Iron- Marked as H
         Mg- Magnesium- Marked as F
         Si- Silicon- Marked as C
         S- Sulfur- Marked as E
         Sn- Tin- Marked as D
         Zn- Zinc- Marked as G
Example of Aluminum

    3) a. Physical property
        b. Physical property
        c. Chemical property
        d. Physical property
        e. Chemical property
        f. Chemical property

This Lab should include:
  • Title- (example- Metal, NM, Metalloid Lab)
  • Purpose- Can be one stated on the handout!
  • Data Table- Data collected in Lab transferred to the google doc
  • Questions- Answered in complete sentences!!!- Questions 1-5
This Lab is shared on a Google doc with your classmates. It is due tomorrow and will be turned in as a group.

The next scribe is.... Peter D.!!! Thanks Peter for taking it!
