B Which sample released the most energy? Different atoms need different amounts of energy to get them to the excited state, and so they release different amounts of energy going back to the ground state. We used these samples: Electrons in excited states do not usually stay in them for very long.
Observe and record the color. Discussion A Which part of the compound is responsible for the flame colour? Dip the splint into the barium chloride so a small amount sticks to the splint.
A special color of flame would appear, then recorded that color. But it produced the same color as sodium nitrate, which showed that the color in which they produce was caused by sodium.
Write an Outline To have a proper, logical paper structure, it is important to come up with an outline. The first one that I will focus on is the Pre Lab questions: What color of light is the lowest in energy? What does it mean when the electrons are "excited"?
During this experiment, we excited the electrons which electrons go to a higher energy level, when electron falls back to ground state, they should emit light. A flame test is a procedure used to test quantitatively for the presence of certain metals in a chemical compounds. Get a notebook or mobile phone writing app to jot down every detail regarding your personal experience.
A written word is more powerful than the one said before. It is important to choose the topic carefully. When the compound to be studied is excited by heating it in a flame, the metal ions will begin to emit light.
Do not forget to insert quotes from the reliable primary sources. This technique of using certain chemical compounds to color flames is widely used in pyrotechnics to produce the range of colors seen in a fireworks display. Photons outside the visible spectrum may also be emitted, but we cannot see them.
In your own words, write a short explanation of how an electron absorbs energy and re-emits it as light and why different elements have different spectra. Mention all works with rights reserved on the last page called Bibliography. The secondary purpose of the lab was to identify unknown compounds that we would test and then guess as to what they were.
Second, when atoms are heated their electrons can gain energy from the heat. A flame test is a procedure used to test qualitatively for the presence of certain metals in chemical compounds.
B Which sample released the most energy? The photons emitted precisely match the quantum energy difference between the excited state and the ground state.
When an electron is in a higher-energy shell it is said to be in an excited state. This gives a way to identify elements by their spectrum. Watch the latest movie before criticizing it in your work.

Three-Paragraph Body An observational essay has a body like any other type of academic assignment:Within the result of the experiment, we can identify metallic ions by using flame tests, because when elements get heated, they emits a characteristic pattern of light energies.
Procedure In this experiment, we used the following materials: 8small test tubes, test-tube rack, paper towel, scoopulas, mL beaker, platinum wire or nichrome wire /5(1).

Flame Test Part 1: Pre-Lab Introduction: In this lab you will conduct a ﬂame test of 3 unknown solutions. You will measure wavelengths of each sample and emitted is a direct result of the Law of Conservation of Energy which states that energy can not be created nor destroyed but can change forms.
This applies to the ﬂame test because as. An observation essay has a lot of common features with the descriptive narrative; play with five human senses. Make sure every page of your paper makes the reader taste, hear, smell, see, and even touch your topic.
