Sodium vapor produces an orange flame when burned. This is commonly seen in street lights and high-pressure sodium lamps.
The reactive metal that gives off an orange glow in streetlamps is sodium. When an electric current passes through sodium vapor inside the lamp, it becomes excited and emits light in the orange part of the spectrum. This phenomenon is known as sodium vapor lamp or sodium-vapor light. Sodium is chosen for its high efficiency in converting electrical energy into light, making it a popular choice for outdoor lighting.

When sodium ions are sprayed over a flame, they impart a yellow-orange color to the flame due to excitation of the sodium atoms. This phenomenon is used in flame testing to identify the presence of sodium in a sample.
Calcium ions burn with an orange flame. When calcium salts are heated, they emit a characteristic orange flame due to the presence of calcium. This can be observed in compounds such as calcium chloride, calcium bromide, or calcium sulfide.
There is almost no sodium in oranges. One medium-sized orange typically contains less than 1 milligram of sodium.
