This question is a little ambigous! If you are refering to the earth's CRUST; oxygen is the most abundant @ 49.2%. But, if you are refering to the WHOLE PLANET; I think iron would be the most abundant, as the crust is just a layer on a huge core [dia about 4300 miles] of mostly iron.

In the Earth's interior the answer is Oxygen...making up 46.6%. Silicon is the second most abundant in the crust. The Core is primarily Iron and Nickle. The Atmosphere is primarily Nitrogen (78%) and Oxygen (19%).
Hope this helps.
