it get's hotter than a burning temperature
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
Generally speaking, metals do not burn. However, with a great amount of heat, metals can bend and lose structural integrity.
Metals cannot 'burn'. Most likely, your 'burning' metal is enriched with other elements that burn. It can melt, it then just melts into liquid metal, then it is still metal.
Most metals do not burn fully like organic materials do. When metals are heated, they often react with oxygen to form metal oxides rather than completely burning away. However, some metals, such as magnesium, can burn in air to form oxides that leave little residue.
they from to liquid form
No. Metals do not burn, only melt.
they form a salt
Metals are not decomposed by heating. Some metals burn, as magnesium.
no
When metals burn in air they form metal oxides.
At a given temperature gases can react with metals.
