Phosphorus (especially white phosphorus) is a nonmetal that can spontaneously catch fire (VERY reactively) in air.
Because is reacts with water causing hydrogen to be released and catch fire. Na + H2O = NaOH + H also it will also float on water having a density of 0.98 g/cm^3
It catches on fire easily. Cotton growing uses a lot of water.
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.
The potassium catches on fire and then explodes. Seriously. Don't try it.
If the surge strip catches on fire, unplug it from the wall outlet and use a fire extenguisher or sand to smother the fire.
