What elements are in fire detectors?
Ionization smoke detectors use a small amount of radioactive material, americium-241, to detect smoke.
What synthetic element is used in smoke detectors?
Americium
How is americium-241 used in smoke detectors?
Ionization chamber smoke detectors contain a small amount of americium-241, a radioactive material. Smoke particles disrupt the low, steady electrical current produced by radioactive particles and trigger the detector’s alarm. They react quickly to fires that give off little smoke.

Is oxygen a metal or nonmetal?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements.
Why Oxygen is a non-metal?
Answer: Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. oxygen and sulfur are therefore know as typical non metals.
