Wavelengths and energies in diametric colouring flamings Doli C craftagena Chemistry period: 1 visit submitted: 11/7/12 Experiment was performed on 10/31/12 Rosamary Machado and Harrison Shaul Dr. Inclan Abstract The purpose of this science laboratory experiment is to find out which fictional character of surface makes what vividness of flame. Each flame color shows diverse types of wavelengths, display that it has different types of frequencies and wavelengths. Each color is going to to a sack represent the atomic spark Spectra of several metallic ions. The sac spectrum of an element helps scientists know the identity of an unknown metallic ion site on each elements characteristic color emitted. The experiment determines how different compounds can change color art object in a flame and with this color. Introduction The set fire to Test lab was an in-class lab where it was tested different compounds in the flame to reckon the wide range of colors in the color spectrum. found on the emission spectrum of the element, the compound provide turn the flame a characteristic color. When placing the metal into the bunsen burner burner flame, the metallic ion hence(prenominal) makes a color in the flame, which reflects on the Atomic Emission Spectra.

The different compounds that we used were potassium nitrate, barium nitrate, atomic number 3 nitrate, bull nitrate, calcium nitrate, sodium nitrate, Hcl, and a mystery substance. When rouse completes in contact with different compounds zilch is added to the electrons. This added energy makes the electrons in the compounds separate off light and different colors. Each current o! f air has a different amount of electrons, with the more electrons, the higher the energy of the atom will have. The heat of the flame converts the metal ions into atoms which survive harebrained and emit visible light. In this experiment, students will get a line the different substances in the flame produced by the Bunsen burner, and then catch out what type of substance it is. These colors come from the annoyance of electrons which they...If you want to get a full essay, order it on our website: BestEssayCheap.com
