Atom: The smallest unit of an element that has all of the characteristics of that element
Protons (P+): Positive subatomic Particles; Found in the nucleus
Neutrons(No): No charge; found in the nucleus
Electrons (E-): Negative subatomic particles; orbit the nucleus
As elements become energized, and then relax, they release light(hv). This light is a different color for every element. We burned substances containing different elements to look at the colors. Here are the Elements, the substances they were in, and the colors that were released when it was energized with fire:
Li(Lithium): Lithium Chloride: Red
Na(Sodium): Sodium Chloride: Yellow Orange
K(Potassium): Potassium Chloride: Violet
Sr(Strontium): Strontium Carbonate: Red Orange
Cu(Copper): Copper Sulfate: Green
Mg(Magnesium): Magnesium: White
B(Boron): Boric Acid: Green (Light)
Spiderman: Copper Sulfate mixed with Lithium Chloride: Blue and Red
-We attached a bunsen burner to a lab stand to keep it and the propane tank secure. After it was lit, people were selected to burn the different elements. For most metals, they were in a powder form. Andrew added methanol to make it flammable, and then the volunteer would hold it above the flame. We would all record the flames color thereafter. After, the metal spatula was placed in water to cool, and wiped with a wet rag to clean off the last element.
-Andrew explained to us why the elements give off colors. As an element is energized, they get farther from the center of the atom. When it relaxes, it uses the same amount of energy to return to the center, and releases the same amount of energy in wavelengths. The wavelengths then are seen by us in different colors.
