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
The most abundant elements in earth's crust are a nonmetal a metalloid and two metals what are the four elements?
The most abundant element in the earth's crust is a non-metal, oxygen. The second is the metalloid, silicon. The third and fourth are the metals, aluminum and iron.
What are the most abundant elements in the ocean?
Hydrogen and oxygen are technically the most abundant elements, as they are the constituents of water (H2O). Excepting those two elements, chlorine, as chloride ions, is the most abundant element, followed by sodium ions.
Why are oxygen and silicon the most common elements found in minerals?
Silicon and oxygen are two of the most abundant elements in the universe. Oxygen will readily bond with silicon and metals to form minerals. Other similarly abundant elements either sank into Earth's interior or tended to form volatile compounds that were driven away from Earth by the solar wind when the planets were still forming.
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 are the two most abundant elements in a main sequenced star?
The two most abundant elements in a main sequenced star are Hydrogen(H) and Helium(He).
What are two elements which are abundant in nebulae?
