The Earth's core is thought to be predominantly iron (85 %) with some (4-5%) nickel and the remainder oxygen, silicon, hydrogen and carbon and a number of siderophile (iron liking) elements that descended to the core with iron during planetary differentiation.
The element that makes up most of the earths CORE is iron.
Iron makes up most of the Earth's core.

Iron and nickel
Iron is the primary element that makes up most of Earth's core, both the inner and outer cores. This iron is primarily in a liquid state in the outer core and a solid state in the inner core due to high pressures and temperatures.
The most abundant element in both the Earth's inner core and outer core is iron. It makes up about 85% of the Earth's core composition.
The principle element found at the Earth's core is iron.
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.
It makes up the majority of the molten core of the earth.
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
The sun consist mainly of hydrogen which makes up about 75% and helium about 25%. Helium is produced in the sun's core as it burns hydrogen. There are smaller amounts of other materials, but these are less than 1%. There is no element which makes up about 10% of the sun.
Iron is an element. It has an atomic number of 26, and by mass, it's the most common element that makes up the Earth ... a large part of Earth's core is iron. Iron is the only element in pure iron.
