What element whose name light-bearing burns spontaneously in air?

Phosphorus is the element that ignites spontaneously in air due to its high reactivity. When exposed to oxygen, phosphorus can catch fire and burn brightly, producing light, hence the nickname "light-bearer."


Which element shows spontaneous combustion?

Phosphorus is an element that can exhibit spontaneous combustion when exposed to oxygen. This occurs because phosphorus ignites spontaneously in air due to its high reactivity, leading to combustion without an external ignition source.


A material that will spontaneously ignite and burn when exposed to air is called what?

A material that will spontaneously ignite and burn when exposed to air is called pyrophoric. Pyrophoric materials are highly reactive and can pose fire hazards if not handled properly.


What is unsual about potassium?

Pure potassium (Element K on the periodic table) Is the most reactive metal. So reactive that it will spontaneously oxidise when exposed to the air and will explosively combust when placed in water.


What element turns white when exposed to air?

Phosphorus is an element that turns white when exposed to air. When pure, it is a colorless and transparent waxy solid.


Wax like transparent solid that ignites spontaneous in air?

The substance you're describing could be white phosphorus. White phosphorus is a highly reactive and pyrophoric substance that can ignite spontaneously when exposed to air. It is often used in military applications, but its use is restricted due to its extreme flammability and toxicity.


Why does a car misfire when going down hill?

The compression in the cylinders is so great that the fuel/air mixture ignites spontaneously (before the spark plug fires)


Why red phosphorous is stored inside water?

Because it is very unstable. It spontaneously combusts when exposed to the air.


Is Indium Stable?

Indium is a stable metal under normal conditions, meaning it does not spontaneously react with air or water. However, it is susceptible to oxidation when exposed to air over time, forming a dull oxide layer on its surface.


What material that has been tested to ignite without an external ignition source within five minutes of being exposed to air?

Spontaneously Combustible


What element when exposed to air produces a violet vapor and extremely unpleasant odor?

Iodine


Why is phosphorus so reactive?

Phosphorus spontaneously ignites on contact with air, producing toxic fumes (phosphorus oxides). Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds.
