10.Most salt contain a metal and a non-metal. Look at the compounds we tested and explain how we can be sure that it is the metal atoms that are responsible for the colors that you see. Metal atoms are responsible for the color because metals reflect high frequency light, non-metals can not do that.

Metal Ion Flame Test Colours Chart – Compound Interest

Feb 06, 2014· Metal Ion Flame Test Colours Chart. This graphic looks at the colour of various metal and metalloid ions that occur during flame tests. Most people probably remeer doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours follows

Science made alive: Chemistry/Experiments

Many metal ions give a color to fire and flames. This phenomenon is used extensively in pyrotechnics, but it also can be used to make nice colored fire, without the need of pyrotechnics. Simply dissolving a suitable metal salt in alcohol and then burning a piece of paper tissue, soaked in the alcohol gives a colored flame.

What colour is imparted to flame by francium and its salts

A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element''s characteristic emission spectrum. The color of flames in general also depends on temperature; see fla

Discover the Flaming Colors of Fireworks | STEM Activity

From the time fireworks were invented (the earliest documentation is from around the 7th century C.E. in China) until the 1830s, all fireworks were either white or orange. Then, in the 1830s, the Italians discovered that adding metal salts to the fireworks mixture resulted in interesting colors, just like in the flame test in this science activity.
