hold the wire in gas flame. Chlorides produced from the substance will readily vaporize in gas flame and create excitations to higher energy levels. During falling back to the ground state some elements may reveal themselves by emission of characteristic colors such as sodium with...
a method of testing for the presence of certain elements by the characteristic color imparted to a flame; as, sodium colors a flame yellow, potassium violet, lithium crimson, boracic acid green, etc. Cf. Spectrum analysis, under Spectrum. See also: Flame Webster's Revised Unabridged Dictionary...
I'm a little stuck on this one as i did not had enough time to analyse my experiments in class. i've tryed to figure out the relation between an element and the color of flame produced by i'm really confused. So my question is How can i determine an unknown element when i know ...

Flame tests rely on the unique electron configurations of each and every element in order to identify them. When in compounds as these elements often are, they exist in the form known as an ion. A metal ion exists when the atom releases its valence electrons to bond with a non-metal atom...

the flame test is not definitive. It is merely one tool available to help identify the elements in a compound. When conducting a flame test, be wary of any contamination of the fuel or loop with sodium, which is bright yellow and masks other colors. Many fuels have sodium contamination. ...
The flameless candle100may further include an underside, as depicted in FIG.2. The underside may include a battery door114and user interface elements190. The battery door114can be opened to remove/place batteries into the flameless candle100. The user interface elements190allow a user to interact...
