Hydrogen and Oxygen.
A water molecule is made of two hydrogen and one oxygen atom.
The water molecule contains two different elements chemically combined, which makes it a compound. A compound is a pure substance that contains two or more different elements chemically combined.
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
two or more different elements
Two elements are combined together in water: hydrogen and oxygen. Water has a chemical formula of H2O, which means each water molecule contains two hydrogen atoms and one oxygen atom.
Sand essentially contains silicon dioxide (SiO2) and oxygen.
Hydrogen and Oxygen
Hydroden and oxygen. H2o
Water is H2O, two hydrogen atoms and one oxygen atoms.
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
Chemical elements are combined to produce chemical compounds.
atoms of hydrogen and oxygen chemically combined to form water
Compounds are formed when elements of matter are chemically combined.
