What are combined elements?
It refers to any two or more elements which have been combined naturally.
Which chemicals occur naturally in the air?
I wouldn't say that many chemicals occur naturally in the air, however Oxygen and Nitrogen are the two main gases that make up the Earth's atmosphere.
In what two way can elements occur in nature?
Some elements occur in nature in a pure form, and not as part of a compound with other elements. Elements such as copper, silver, and gold are also minerals. Almost all pure, solid elements are mentals.
What elements or compounds are made from two molecules?
No elements can be made from molecules, because molecules are made from elements instead. If the question is really, "What elements normally occur in nature as diatomic molecules?", the answer is hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine.
What two elements are combined to make fusion occur?
Two elements to begin are hydrogen's to make a neutron (deuterium) then after helium is fused (three) to make carbon and two carbons to make a magnesium-24. So vague question.... Cosmic Ray...www.ScienceIsGolden.com
Which two actinides occur naturally?
Uranium and Plutonium are the only elements from the Actinides series that occur naturally on Earth, though they are rare.
Do all the 116 known elements occur naturally on Earth?
No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.
What are two types of elements from or in the periodic table?
Naturally occurring and man made elements
What are combined elements?

Where does an elephant occur naturally?

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.
Where do get water from?
Water is a compound of Hydrogen and Oxygen (H2O) and is formed naturally when the two elements meet in the right conditions.
When two elements are mixed to form a compound how does this occur?
Electrons are shared or swapped between atoms.
How many diatomic gaseous elements are found naturally on the earth?
There are only two elements, nitrogen and oxygen, that occur in any quantity as simple substances in diatomic gas form. The mixing ratio of dihydrogen gas in the lower atmosphere is around 500 parts per billion, so that would make three if we are really scratching around.
