Timothy Johns Christian Howard Wan Huang 10/18/12 Flame Test Lab Introduction Spectroscopy is the study of the electromagnetic radiation emitted or absorbed by atoms and molecules. These studies are very helpful in determining an unknown element‚ given the fact that all elements burn a different color. The flame colors vary because of the different amounts of energy the elements give off. This lab is made for the learner to determine the identity of two unknown elements. Hypothesis If

ACTIVITY FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light is made up of a mixture of all the wavelengths of light. Light‚ consisting

Flame Test Lab Morgan Chemistry CP 5/30/14 Abstract- In the flame test lab‚ the flame test was performed to excite the electrons in the samples and observe the color of the flame. The flame emits a color because each element has an exactly defined emission spectrum‚ which one can use to identify them. For example‚ NaCl was highlighter yellow‚ Sr(NO3)2 was sun orange‚ CuCl2 was turquoise‚ LiCl was neon red‚ KCl was solar flare yellow‚ and BaCl2 was Voldemort green. Introduction- In Bohr’s

found in a compound. And in order to detect the presence of metals in a compound‚ flame test is done. The result of the flame test is based on each element’s characteristic which is emission spectrum. Flame test involves placing a sample of an element or compound in a non-luminous flame and observing the resulting color of the flame. Flame test is fast and easy to perform. All the equipment needed for flame test is present in all chemistry laboratories. Solubility is a quantitative term defined

Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

molecules. A photon in short is light. Atoms produce light by putting energy in‚ the electron then becomes excited and goes up an energy level‚ the electron then falls back down to its ground state‚ and out comes a photon (light). The electromagnetic spectrum contains color that we can and cannot see. The color blue has the highest energy with shorter wavelengths and a higher frequency while the color red has the lowest amount of energy with long wavelengths and a shorter frequency.
