What is the most abundant element in entire earth?
There is incomplete info on the core, but Iron is likely to be it. However, since many elements in the crust are oxides and if you include water and atmospheric oxygen current information points that oxygen is the most abundant element on earth at about 45-50% of the Earth's mass (note its also the 3rd most abundant element in the universe) but element of the earth would be hydrogen (H) for every 1 oxygen on the earth there is 2 hydrogens (in normal air situations)Good answer=)(a wiki answers user was here..... not him^^^^^)Oxygen is the most abundant element in the earth's crust.
