Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

Flame Test Lab Introduction/Purpose: When a certain amount of energy is supplied within an atom‚ the electrons of that atom begin to move up the levels of electron configuration. This level of energy is called a quantum. The object of this experiment was to examine the movement of electrons up and down energy levels through the use of given elemental substances. With heat supplying a large amount of energy‚ the properties of the elements caused them to give off a certain color or tone of

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

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

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

Chemistry 02 Oct 2014 Flame Test Lab Purpose: To find out the unknown compound from known compounds and the color of the flame. Safety & Precautions: •Do not cross contaminate compounds. •Keep goggles on at all times when working on lab. •Long hair should be tied up to avoid being singed.

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

Livana Partners : Rachel Gideon‚ Joy Boake‚ Hannah Harper Various Color of Light as the Effect of Electron 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
