No. It's a whole bunch of (mostly nasty and/or toxic) compounds.
No, smoke is not considered an element. Smoke is a mixture of particles and gases that are produced when a substance undergoes combustion.
The element used in smoke detectors and named after the US is Americium (Am). It is a radioactive element commonly found in household smoke detectors to detect smoke particles in the air.
Dude... what?
Cigarette smoke is not an element. Elements are made of only one type of atom, cigarette smoke contains all type of atoms and particles, many (if not all) of which are toxic.
It is a mixture.
The synthetic element used in smoke detectors is Americium-241. It emits alpha particles that ionize the air within the smoke detector, causing a small electric current flow. When smoke particles disrupt this current, an alarm is triggered.
Americium (pronounced /ˌæməˈrɪsiəm/) is a synthetic element that has the symbol Am, the atomic number 95, and is used in smoke detectors.
Americium 241
The smoke detector.
Yes
No, smoke is a substance of very, very tiny solid particles dispersed in air.
Americium is the radioactive element used in ionization type smoke detectors. It is a by-product of the nuclear power industry. In the device, it is present as the oxide, which is rather chemically inert and has a high melting point. As a small capsule enclosed in metal foil. Your exposure to radiation from an ionization smoke detector is smaller than your exposure received by sleeping alongside your partner who is converting K40 into Ar40.
