Elements lab Report

Purpose:

To classify elements based on their properties.

Hypothesis:

None needed for this investigation.

Materials:

Five different elements that you can observe online or in person.

(You may check your periodic table for ideas).

Procedure:

Step 1.

Elements Symbol Colour State Metal, nonmetal or metalloid Conductivity Magnetic
Carbon C Black Solid Non-metal No No
Mercury Hg Silvery white Liquid at room temp. Metal Yes No
Neodymium Nd Silver grey Solid Metal Yes Yes
Silicon Si Reflective with bluish-tinged face Solid Metalloid No No
Helium He Colorless Gas Non-metal Yes No
Bromine Br Reddish Brown Liquid at room temp. Non-metal No No

Questions:

1.   Metals: Hg, Nd/Non-metal: He, Br, C/Metalloid: Si

2.   Hg, Nd, and He

3.   a) Solids at room temp – Exception: Mercury

b) Silver grey – Exception: Gold, Copper

c) Shiny – Metallic luster

4.  a) Found in all states (solid, liquid, gas)

b) Different colors

c) Without metallic luster

Conclusion:

In this experiment, I learnt that helium is actually a great conductor, and that is actually not a conductor at all (I thought it was a semiconductor). I also learnt the different colors, states, symbols, and magnetism of each element. In the future I would like to perform the same experiment but on a larger scale and with more or all the elements.
