Such substances are called pyrophoric. Most are actually igniting in response to water vapour in the air, but it doesn't necessarily have to be that humid for them to start burning.
On the list are,
* iron sulfide;
* depleted uranium (if sliced thinly or powdered);
* other finely divided metals (including magnesium, calcium, zirconium)
* Aakali metals (sodium, potassium)
* metal hydrides or nonmetal hydrides (germane, diborane, sodium hydride, lithium aluminum hydride, uranium trihydride)
* grignard reagents (compounds of the form RMgX)
* fully or partially alkylated hydride derivatives(e.g., diethylaluminum hydride, trimethylaluminium, butyllithium, triethylboron)
* alkylated metal alkoxides
* nonmetal halides (diethylethoxyaluminum, dichloro(methyl)silane)
* metal carbonyls (iron pentacarbonyl, dicobalt octacarbonyl, nickel carbonyl)
* used hydrogenation catalysts, including Raney nickel (very volatile because of extra hydrogen already attached to it)
* phosphorus (white, yellow)
* plutonium
* methanetellurol (CH3TeH))
Some gases are prone to such combustion, including * Arsine, Diborane, Phosphine, Silane, and the liquid hydrazine. Also metalorganic liquids.
Some types of coal, caseium rubidium, silanes, and boiled linseed oil can also ignite when just exposed to ordinary air.

What causes carbonite to explode?
Carbonite explodes because the mixture of ingredients are volatile and when exposed to to something like fire with be set off. It is commonly used in the mining industry.
What does flamability mean?
something that catches on fire.
Why does petrol catches fire easily?
Petrol catches fire easily because it is a highly flammable liquid that evaporates quickly at room temperature, creating a mixture of vapor and air that is easily ignitable. Additionally, petrol has a low flash point, which is the temperature at which it can produce enough vapor to ignite when exposed to a flame. These factors make petrol highly flammable and pose a fire risk.
Why does potassium sink in water?
K catches fire in water .
Is flammability a physical or a chemical?
Flammability is considered to be a chemical and not a physical change. This based on the fact that combustion will take place which is a chemical reaction.
What is the flamability of sodium?
It readily catches fire when exposed to oxygen.
If a pickup truck catches fire in the engine will the truck explode when the fire gets to the gas tank?
No. A fuel tank will not explode just because it is on fire. However, it will feed the fire and make it worse.
What is used in fire grenades?
White phosphorus, it is a chemical that catches fire on contact with oxygen.
How does a fire start?
when a flammable chemical such as oil (ancient tree) gets heated up to much it acts as a chemical reaction it catches on fire
What is the statement methane as a gas that easily catches fire describe?
The statement "methane as a gas that easily catches fire" means that methane is highly flammable and can ignite easily when exposed to a flame or spark. This characteristic makes it a significant fire hazard if not handled properly, as it can lead to explosions or fires.
What is the property that describes how easily a substance catches fire and burn?
The property that describes how easily a substance catches fire and burns is called flammability. It measures the ability of a material to ignite and sustain combustion when exposed to a heat source.
When placed in H2O a sodium pellet catches on fire as hydrogen gas is liberated and sodium hydroxide forms chemical or physical change?
This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.
What happens when the firewall on your computer catches fire?
Your computer melts and then explodes due to the chemical reaction of the components. Tough luck.
When placed in H2O is a sodium pellet that catches on fire as a hydrogen gas is liberated and sodium hydroxide forms a chemical change?
Yes.
What should do if your surge strip catches on fire?
If the surge strip catches on fire, unplug it from the wall outlet and use a fire extenguisher or sand to smother the fire.
Why sodium metal catches fire?
Sodium metal catches fire when exposed to air due to its high reactivity. It reacts with moisture in the air to form sodium hydroxide and hydrogen gas, which ignites due to the heat generated from the reaction. The heat produced is often enough to ignite the hydrogen gas, resulting in a fire.
Why should you never put a spray can in a fire?
Spray cans can explode when exposed to heat, leading to fire hazards and potential injury from flying debris. The pressurized contents of the can can also ignite and contribute to the intensity of the fire.
