Flame Tests

This table of flame coloration is modified from the book "Determinative Mineralogy and Blowpipe Analysis" by Brush & Penfield, 1906. The colors are best observed by heating the sample on a loop of platinum wire moistened with HCl. The spectra are calculated to represent the emission from a flame and are based on the work of John Talbot.

Why do different elements burn different colors during a

Mar 19, 2009· Best Answer: Flame colours are produced from the movement of the electrons in the metal ions present in the compounds. For example, a sodium ion in an unexcited state has the structure 1s22s22p6. When you heat it, the electrons gain energy and can jump into any of the empty orbitals at higher levels - for example, into the 7s or 6p or 4d or whatever, depending on how much energy a …

Chemistry Experiment: Flame Tests (Li, Na, K, Ba, Sr & Cu

Keller, Chemistry Teacher, demonstrates the different colors that can be produced in a flame by the use of different metallic salts. When ions of the metallic elements in each salt are heated their electrons become excited. Excited electrons drop back down to lower energy levels and release light of very specific colors in the process.
