Answer:
Magnesium burns easily.
It burns in O2 with a dazzling white flame.
The magnesium metals becomes magnesium oxide (MgO), which is a silvery white powder.
Na>Mg>Al>Zn>Fe>Pb>Cu
All metal oxides are generally insoluble in water. Exceptions include sodium oxide, barium oxide, pottasium oxide, strontium oxide etc.
In this case, all the oxides are insoluble in water except sodium.
Hope its clear...
Plz mark me as BRAINLIEST if u thnk I'm right... :)
