WebHow did the flame test provide evidence that specific atoms are present in compounds? The color of the flame produced during the flame test is a chareristic of particular metallic elements. When a compound containing one of the metallic elements is heated, its atoms emit light of a specific color. WebMar 10, 2024 · The test carried out to detect certain elements in a compound is known as Flame Test. Consider the following explanation :- When elements are burnt or in heated in a flame, the electrons in the atoms of such elements are excited to higher energy states. On de-excitation from higher to low energy level, these electrons emits photons (light) of …
WebWell, a kind of spectroscopic library of elements was compiled using flame tests. A known element, uh, say a piece of iron for example, is heated in a pure gas flame. The iron eventually heats to the point that it radiates light. 选项分析 ： 学生问，怎样才能知道pattern和element的对应关系。教授提到了flame test。
