Interpretation : A strontium compound burned in a flame emits red light, and a barium compound heated in a flame emits yellow-green light. The reason for these colors emitted is to be explained.
Concept Introduction : The electrons in atoms migrate to higher energy levels when they absorb energy. When these electrons fall in energy, they lose energy by releasing light.
Answer to Problem 26LC
The electrons are returning to lower energy levels by emitting light. Since each element has a unique emission spectrum different colors are emitted.
Explanation of Solution
Light from a compound is produced when the electrons lose energy and return to the lower energy level.
All elements have a distinct color because each has a unique electron emission spectrum.
Due to the emission of
