Magnesium and copper metals are heated directly over a flame.Which of the two will burn in the air?
Answer:
Magnesium will burn. If you have never seen a magnesium ribbon burned, it burns extremely bright and extremely hot (2200 °C or 4000 °F.)
Magnesium metal will burn in air,since magnesium is much more reactive than copper in reactivity series.

try with magnesium ribbon.. be carefull!!
Mg
Magnesium will burn with a bright glow in the air to form magnesium oxide.
magnesium
Mg
Magnesium will burn, giving a bright white flame & if the sediments are mixed in water it will make magnesium hydroxide which is a base
Magnesium will burn, copper will not. Magnesium is a Group 2 element, lower atomic weight than copper, with type s and p electrons only, more reactive in air. Copper will melt in flame, not burn, because it is a transition metal which includes s, p and d electrons and this leads to more stability.
hi tanima, it is simple , Mg will burn bcoz magnesium is an alkaline earth metal, it is highly electropositive, needs to loose its two valence electrons to acquire table nearest noble gas configuration(Ne) , o in air it reacts with O2 at high temperature forming MgO2,all right
Magnesium will burn.Melting point of Mg is 651 degrees celcius whereas melting point of copper is 1083 degrees celcius.
Definitely Magnesium will burn in the air first. If you have put both the metals together over a flame to experiment, and if enough high heat is generated, Copper may follow it.
Magnesium is comparatively a active element - sensitive to many physical and chemical attacks. It reacts with Oxygen readily at very moderate conditions.
Magnesium burns with very bright luminous light, almost equal to sunlight and therefore - during second world war Magnesium stripes were used to find out the black-out area during air attacks in the night.
Magnesium was also used in the flash-gun of Photographers till recent past. These flash bulb were having Magnesium filaments and Oxygen in it, which was ignited by a battery spark. These were only once used type.
