And does rubidium ignite spontaneity in air...in powder phase or small piece of metal.

Alkali metals are a group of highly reactive elements including lithium, sodium, potassium, rubidium, cesium, and francium. When exposed to air, they can react vigorously and sometimes violently, producing heat and light.
Yes, alkali metals can burn at very low temperatures in air. This is because they have a low melting and boiling point, making them highly reactive even at low temperatures.
When alkali metals burn at low temperatures in air, they undergo a chemical reaction with oxygen, producing an oxide compound and releasing heat and light. This reaction is highly exothermic and can be dangerous if not properly controlled.
Alkali metals have a single valence electron in their outermost energy level, making them highly reactive. This electron is easily lost, allowing the metal to form a positive ion and react with other substances like oxygen in the air.
When handling alkali metals, it is important to wear proper protective gear such as gloves and goggles to prevent contact with the skin or eyes. They should also be stored in airtight containers to prevent any reactions with air. It is also recommended to conduct experiments in a fume hood to prevent any potential hazards.
