Is Fire and element or compound?

Answer 1

No. Fire is not an element and it can never be or was! It was one of the 1000s or even millions of ancient and medieval proof-less, funny, unscientific, and false believes/thoughts that Fire is one of the fundamental things everything in this material world (including us!) and even heavenly bodies are made up of 5 elements/panchaboothas. Both Greeks and Indians are among these. There are no such elements called sky/space/akasha/ether, Earth/bhoomi, Fire/heat, Water, and Air/Vaayu. We are not made up of any of these elements apart from water. Unfortunately, there are many people around the globe who still believe in this myth. Do not blindly believe in anything without proof(s) whether is science or religion! There is no such rule that belief(ies) of majority of people should be or will be true ;-)

Fire: Combustion or burning, in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke. - New Oxford American Dictionary, 2009.

Element: Any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simpler substances and that singly or in combination constitute all matter - WordWeb.

Answer 2

Neither, Fire is a result of a chemical reaction with oxygen and some other chemical or element. For example, in a burning log, the wood is reacting with another substance and oxygen to give off flame.

Answer 3

Fire is not an element or a compound. It is a physical reaction (combustion) that releases heat and light energy when a fuel source combines with oxygen in the atmosphere.
