Question

During a flame test, a lithium salt produces a characteristic red flame. This red color is produced when electrons in excited lithium atoms
1. are lost by the atoms
2. are gained by the atoms
3. return to lower energy states within the atoms
4. move to higher energy states

Answer 1

During a flame test, a lithium salt produces a characteristic red flame. This red color is produced when electrons in excited lithium atoms return to lower energy states within the atoms.
