WebList elements in the flame test from the order of energy being emitted. Strontium, Sodium, Calcium, Barium, Copper, Lithium, and Potassium. Limitation of Flame Test It cannot detect low concentrations of most ions. ROY G BIV The energy of colored light increases in this order. Which elements are the least easily identified? Sodium and Potassium WebShare the results from the flame tests, if a class experiment was done. Give each student a copy of the periodic table, or ensure one is available. Lead the discussion as the groups give their answers to the two questions: For question 1: The metallic elements in the compounds create different colours. Their ions have different structures.

How Flame Test Colors Are Produced - ThoughtCo
A flame test is an analytical procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element's characteristic flame emission spectrum (which may be affected by the presence of chloride ion). The color of flames in general also depends on temperature and … See more The test involves introducing a sample of the element or compound to a hot, non-luminous flame, and observing the color of the flame that results. The idea of the test is that sample atoms evaporate and since they are hot, they … See more The flame test is relatively quick and simple to perform and can be carried out with the basic equipment found in most chemistry laboratories. However, the range of elements positively detectable under these conditions is small, as the test relies on the See more • Bead test • Spark testing • Colored fire • Emission spectrum See more • Flame Test - Coloring Fire - Pictures of Several Flame Tests, Includes Instructions • WebMineral.com - Flame Coloration by Element See more Web1 / 13.
