GENERAL KNOWLEDGE

Detailed explanation-1: -White phosphorus is the form that occurs most commonly at room temperature. It is very reactive. It combines with oxygen in the air very easily. It catches fire spontaneously when exposed to air.

Detailed explanation-2: -Phosphorus is a non metal that catches fire when exposed to air. It is a highly reactive metal and spontaneously reacts with oxygen to catch fire. Phosphorus is a non metal, which occurs in three forms white, red and black White phosphorus appears translucent.

Detailed explanation-3: -Alkali metals react with air to form caustic metal oxides. The heavier alkali metals (rubidium and cesium) will spontaneously ignite upon exposure to air at room temperature.

Detailed explanation-4: -It is very reactive non-metal which does not react with water. It immediately catches fire when exposed to air. To prevent this, it is stored in water.

Detailed explanation-5: -The only nonmetal is the white phosphorus that reacts with air to form its oxide by burning. Nonmetals usually don’t react with water. Except for chlorine, chlorine dissolves in water to produce an acidic solution.
