Dalton discovered this in 1803.
atoms of hydrogen and oxygen chemically combined to form water
Compounds are one or more elements combined to make a compound. Like H2o is oxygen and hydrogen combined.
In chemistry, a compound (C) contains different types of elements joined together through chemical bonds. These elements can be atoms of different elements, such as in water (H2O), where hydrogen and oxygen are combined. Compounds can exhibit unique properties that differ from the individual elements that make them up.
It the same way that 26 letters of the Roman alphabet can be combined together to make all the words in the English language - and similarly for most other languages - elements can be combined to make compounds. Elements and compounds can form mixtures and these three types account for most normal matter.
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
Hydrogen and Oxygen
Hydroden and oxygen. H2o
Yes, chemical compounds are made up of elements combined together.
two elements hydrogen and oxygen is used to make water i.e H2O . there are two molecules of hydrogen and one molecule of oxygen
Elements are combined into molecules, which, when combined in big groups, make up the things that are around us. Ex: H = Hydrogen, 0 = Oxygen, H₂O = Water
atoms of hydrogen and oxygen chemically combined to form water
When two or more elements are combined to make a compound, water, the new compound can have completely new properties(water is a liquid at room temperature ,while hydrogen and oxygen (elements in the water) are both gases at room temperature),or they can have similar properties to their elements
Na:Sodium Cl:Chlorine NaCl= Salt
Almost all elements can be combined into compounds, for example water=h20 steel=iron and carbon. Their properties usually change. For example when carbon is added to iron to make steel, it becomes stronger and more durable. Humans use compounds to our advantage, adding various elements to materials to make them water proof, stronger, more flexible, harder e.g
two or more different elements
It depends on what elements it combines with and in what arrangement. There are many compounds of arsenic.
