51% of it is
You are thinking of the Earth's core, which is primarily iron, with nickel and a variety of other elements in smaller percentages; the Earth's surface has a much more varied chemical composition, which you should be able to observe, since we all live on the surface.
no it is not true. there is solid iron and nickel in the Earths core
nickel and iron
The Outer Core has magnetic field and it is made out of iron and nickel
Mainly iron and nickel.
In a liquid state.
An alloy of solid nickel and iron, mostly.
The Earth's core is mainly made up nickel and iron. John Doe - Geology Major
IronNickeland then everything else in much smaller quantities.
Iron, nickel and possibly oxygen (the idea is debated) there is about 4%nickel but im not sure about how much iron there is, but over 85%. hope this helps :)
The way I understand it, entirely.
Although we can not see them, we know from certain meteorites (Nickel/Iron meteorites) and from the density measurements of the rocks we see at the Earth's surface compared to the mass of the whole planet that the two most abundant elements in the Earth's core must be Iron and Nickel. Iron being the predominant of the two.
