H2+O2--> H2O

formation of covalent bond, it should be a slow reaction.
Yet why H2O formation is quick??

Does it imply that, oxidation of non-metals are slow?
Or metal oxidation is all slow????????????

This statement is not correct. The strength of the bond being formed is only one of the factors affecting the rate of reaction.

Not really. Oxidation of many non-metals is quite fast.

[quote] metal oxidation is all slow???????????? [/quote]
Many of them are fast, yet some metals do not react directly with O2 under normal conditions (e.g. noble metals)
