ABSTRACT: Flame Photometry also known as flame atomic
ABSTRACT: Flame Photometry also known as flame atomic emission spectrometry is a branch of analytical science that examined the species in form of atom, mostly it works on principle of ionization of alkali metal salt drawn into a non-luminous flame.
FLAME TEST AND ATOMIC SPECTRA LAB
Certain metal ions will turn the flame very distinctive colors; these colors in turn can help identify the presence of a particular metal in a compound. However, some colors are produced by several different metals, making it hard to determine the exact ion or concentration of the ion in the compound.
Different metal electrons emit different wavelengths of light to return to their respective ground states, so the flame colors are varied. These flames can be used to produce atomic emmision spectra of the elements cousted. Using known values of emmision spectra, one can perform a flame test on un unknown substance, gather an emmision

What causes different colors in flames?
What causes different colors in flames? Asked by: Jimmy Willard Answer Colors in general result from either emission of light of specific wavelengths, or absorption of light of specific wavelengths from a mix of photons. At the root of both emission and absorption is the excitement of electrons.
Calcium is a mineral that is crucial for proper formation of strong bones and teeth. It also plays a vital role in maintaining regular heartbeat and the proper transmission of nerve impulses.Calcium stores determine the effect peristaltic action of the intestines and the health of muscle fiber.This mineral is also necessary for blood clotting and is believed to help prevent the development of

Experiments: Flame Test: Nichrome Wire
Place tip of nichrome wire in flame until there is a constant orange/yellow color. Dip the tip of the nichrome wire into a salt (only put one or two crystals on the tip). Place the tip of the nichrome wire (with salt on it) in the flame. Observe the color of the salt as it …
Chemistry: Flame Test Lab | Essay Example
It will appear to be one color, which is carefully described. A flame test is a procedure used to test for the presence of certain metals in a chemical compounds. When the compound was excited by heating it in a flame, the metal ions began to emit light. Due to the emission spectrum of the element, the compound turned the flame a certain color.
Flame Test Lab - Rachel Edwards'' Digital portfolio
All metals produce a different color flame due to different amounts of energy being released. The flame color may be extremely similar but, not exactly the same. Discussion of Theory: In this experiment our goal was to be able to determine a compound based on the color of flame it produced. I believe we were successful in doing so.
Flame Tests Lab Report Free Essay Example
The metal in the compound was identified by the light orange color seen during the flame test. Table 1 proves my hypothesis to be correct. Conclusion- 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 …
Using Flame Tests to Identify Metal Ions - Video & Lesson
Metal ions are positively charged atoms that give off a characteristic color during the flame test. When thermal energy is absorbed by the electrons in the metal ion, they jump to a higher orbital .

When you burn gold, what colour is the flame? | Yahoo Answers
Sep 15, 2011· Flame tests are used to identify the presence of a relatively small nuer of metal ions in a compound because of spectral interferences and also not all metal ions give flame colorsgold has a spectra in the visible region but need more energetic excitation sources than the ordinary Bunsen burner flame therefore gold would not exhibit any color when burnt.
Painting Gorgeous Colors onto Copper Using Only An Open Flame
Sep 02, 2015· The colors are further altered by using the flame to consume oxygen near the surface of the metal. This gives the artists more control over the color transformation process by preventing the oxygen from further changing the color dynamics. Colors and patterns are made, then the metal is cooled with a fan.
