* Calcium (Ca): Burns with a red-orange flame and produces a white ash.
* Lithium (Li): Burns with a crimson red flame and produces a white smoke.
* Iron (Fe): Burns with a bright orange glow, especially in powdered form.
* Aluminum (Al): Burns with a very bright white flame when finely divided.
* Titanium (Ti): Burns with a brilliant white flame and produces a white smoke.
The ability of a metal to burn in air depends on factors like its reactivity, melting point, and surface area. Highly reactive metals like alkali metals (sodium, potassium, etc.) burn readily in air, while less reactive metals like gold and platinum do not.
It's important to note that burning metals can produce harmful fumes and should be handled with caution. Always follow proper safety procedures when working with metals and flames.
