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.

Iron & Nickel.
How do we know??? Sound/Earthquake waves sent from one sides of the Earth to the other, travel at given speed . For each type of material that speed can vary. Having tested for iron and nickel on the surface, then by extrapolation it is found to be iron and nickel in the centre.
Also the Earth has magnetic poles, and iron and nickel both can act as magnets. If they didn't exist in the centree of the Earth, the Earth would probably not act like a magnet.

What is the most abundant metal In earths core?
Iron is the most abundant metal in the inner and outer core of the Earth.
What is the outer cores most abundant elemant?
The earths outer core's most abundant elemant is silicon. :)
Identify the two most abundant elements in the earths crust?
The two most abundant elements in the Earth's crust are: Oxygen (46.1%/461,000ppm), and Silicon (28.2%/282,000ppm).
Why is iron the earths most abundant element?
It makes up the majority of the molten core of the earth.
What are the two most abundant element in the earths core?
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.
What are the two most abundant elements in earths crust and what mineral group do these elements form?
oxygen and silicon they form silicates, i think
What are the symbols of the 2 most abundant elements found in earths atmosphere?
Oxygen is O and nitrogen is N.
What two elements make up earths core?
The core of the earth contains many elements, not just two.However the two most abundant elements in the earth's core are nickle and iron (the final two elements that a star can make by fusion before it dies).But there are many other elements in the core, especially ones with atomic masses greater than that of nickel and iron. Many of these heavy elements are radioactive (e.g. radium, thorium, uranium) and it is the heat generated by the decay of these heavy radioactive elements that keeps the core hot and the outer core liquid.
What are the 8 elements that make up the earths crust?
The eight most abundant elements making up the Earth's crust from most to least abundant are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
What happens when earths two most abundant elements are combined?
The two most abundant elements in the Earth's crust are oxygen and silicon. When you combine them, you get silicon dioxide; which depending on the exact form it takes is glass or quartz or sand.They tend to combine further with other elements to produce silicate rocks.The two most abundant elements in Earth as a whole are iron and oxygen. When you combine them, you get iron oxide (rust, hematite, magnetite). The reason iron isn't more common in the crust than it is is that it's heavy and has been concentrated in the Earth's core.
What is a member of the boron family and is most abundant metal in the earths crust?
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
