oxogen and hydrogen
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.
Hydrogen and oxygen forming water molecules make up most of the ocean.
oxygen and silicon they form silicates, i think
The two most common elements in Earth's crust are oxygen and silicon. Oxygen makes up about 46% of the Earth's crust by weight, while silicon makes up about 28%.
I think you would say that just a few elements dominate in each of these categories:atmosphere: just two elements, oxygen and nitrogen make up about 99-100%oceans and other waters: oxygen and hydrogen make up about 99-100%solid earth, mainly: oxygen, silicon, aluminium, iron, calcium, sodium, potassium, magnesium, titanium account for around 95%living matter: oxygen, carbon, hydrogen and nitrogen account for around 97%
This question depends on what importance is being assigned. The most common dissolved ions (elemental atoms do not dissolve) are sodium and chloride, but they are many other important elements found in sea water.
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.
Hydrogen and oxygen forming water molecules make up most of the ocean.
Hydrogen and Helium
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.
The exact mix is different depending on the star's age and size, but hydrogen and helium are always the two most prevalent elements.
The two most prevalent elements on Jovian or gas planets like Jupiter and Saturn are hydrogen and helium. These elements make up the bulk of their composition, with hydrogen being the most abundant element in their atmospheres.
The two most abundant elements in nebulae are hydrogen and helium. These elements make up the majority of the mass in interstellar clouds and are the building blocks for the formation of stars and planets.
The two main elements that make up most of Earth's core are iron and nickel. These heavy metals are believed to be the primary components that give the core its dense and solid nature.
By far, the two most abundant elements are hydrogen and helium.
the oceans
The two most common elements in the Universe, and in most stars are - in that order - hydrogen and helium (elements #1 and #2).
