What two elements is earth's atmosphere mostly made up of?
The atmosphere is the mixture of gas molecules and other materials surrounding the earth. It is made mostly of the gases nitrogen (78%), and oxygen (21%).
What are the two most abundant elements in the solid earth?
The two elements that commonly occur within the earth crust are Oxygen and Silicon.
Which two elements make up center earth?
iron and nickel
What are the two most aboundant elements on Earth?
Nitrogen 78 % Silica in soil
The center of the earth is made up of?
the two different elements that make up the center of the earth are iron and nickel. there have been recent studies that there might be other elements there, but we can not know for sure because there has been no artificial (man - made) objects that have been down there.
The mass of the earth is made up mostly of which two elements?
The mass of the Earth is mostly made up of iron and oxygen. Iron is primarily found in the Earth's core, while oxygen is abundant in the planet's crust and mantle.
What are the two most abundant elements by mass found in the earth's crust?
The two most abundant elements by mass in the earth's crust are oxygen and silicone. The crust of the earth typically runs between 20 and 25 miles deep from the surface.
What are the two elements that make up 75 percent of the total mass of the crustal rocks of the earth?
Oxygen and silicon are the two elements that make up 75 percent of the total mass of the crustal rocks on Earth.
Which two elements make up the greatest percentages by mass in earth's crust?
The two elements that make up the greatest percentages by mass in Earth's crust are oxygen and silicon. Oxygen accounts for approximately 46% and silicon around 28% of the Earth's crust by weight.
What are the two most abundant element by mass found in the Earth?
The two most abundant elements by mass in the earth's crust are oxygen and silicone. The crust of the earth typically runs between 20 and 25 miles deep from the surface.
About 75 by mass of Earth's crust is composed of what two elements?
The two elements that make up about 75% of Earth's crust by mass are oxygen and silicon. Oxygen is the most abundant element, making up about 46% of the Earth's crust, while silicon is the second most abundant element, comprising roughly 28%.
When two elements chemically react the mass of the product is?
When two elements chemically react, the mass of the product is equal to the sum of the two masses of the two elements.
What are the two most abundant elements by mass found in Earth's crust?
The 8 most common elements in Earth's crust (by mass): 46.6% Oxygen (O) 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) Therefore, the most common metallic elements in the Earth's crust would be Silicon and aluminum. (Note that aluminum is a metal, but silicon is considered to be a metaliod -- not to be confused with Silicone which is a synthetic polymer.)
What accounts for most of the mass of water?
water is made of two elements oxygen and hydrogen. H2O..being that there are two parts of hydrogen and one part oxygen. then most of the mass of water would be hydrogen.
Anyting that is made on earth is made up of?
A liquid, solid, gas, or plasma. Everything on earth is made of several different elements (such as carbon, nitrogen, hydrogen, etc.) in various combinations and variations and mixtures. These elements all derive from hydrogen and helium from the sun. These two basic elements broke down and aged into the elements that can be found, and are yet to be found, in the periodic table.
Compounds are made made of how many elements?
Two or more elements.
Name two elements that are alkaline earth metals?
Two elements that are alkaline earth metals are calcium and magnesium.
