78% of Nitrogen and 21% of Oxygen
Oxygen and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
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.
oxygen and silicon they form silicates, i think
The two elements that are most abundant in Earth's crust are oxygen and silicon. Oxygen is the most abundant element in the Earth's crust, making up about 46% of its mass, while silicon is the second most abundant element at approximately 28%.
The two elements that make up most of the ocean are hydrogen and oxygen. Water, which is composed of two hydrogen atoms and one oxygen atom (H2O), is the most abundant substance in the ocean.
Oxygen and silicon are the two most abundant elements found in the most common minerals. The most common minerals found on Earth are silicates.
Hydrogen and helium are the most abundant elements in stars.
