It sounds like you are confusing meaning of "substance" with the meaning of "element". A pure element is a single type of atom. A pure compound will contain only one type of molecules. The molecules may be made up of more than one element, but every molecule of the compound will have exactly the same elements in exactly the same ratios and bound in exactly the same structure. All water molecules are the same:: H2O. If the only type of molecule you have is H2O, you have "pure water".
"Substance" just means "a particular kind of matter with uniform properties". Pure water will have uniform properties - note that those uniform properties are quite different from those that are displayed by elements that make it up when in their pure form; at room conditions water is liquid but pure hydrogen and pure oxygen are gases.
Water is a pure substance but it is a compound and is made of oxygen and hydrogen.

What substance contains all type of atoms found in minerals?
Rocks and minerals are made up of various types of atoms such as silicon, oxygen, aluminum, iron, calcium, and others. These atoms are naturally occurring elements that form different combinations and structures to create the wide variety of minerals found in nature.
Is icy water both pure and contains different types of atoms?
All water contains two different types of atoms: hydrogen and oxygen, twice as much hydrogen as oxygen. If its pure water that's all there is in it. The purity of the water has nothing whatsoever to do with its temperature: pure water can be boiling hot, and icy water can be filled with impurities.
How many Atoms are in one molecule of the substance?
The number of atoms in one molecule of a substance depends on its chemical formula. For example, a water molecule (H₂O) contains three atoms—two hydrogen atoms and one oxygen atom. In contrast, a glucose molecule (C₆H₁₂O₆) contains 24 atoms—six carbon, twelve hydrogen, and six oxygen atoms. Therefore, to determine the exact number of atoms in a molecule, one must refer to the specific chemical formula of that substance.
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many elements are in the substance water (H2O)?
Water (H2O) is composed of two elements: hydrogen and oxygen. Specifically, it contains two hydrogen atoms and one oxygen atom. Therefore, in terms of distinct elements, there are two elements in the substance water.
What formula represents a substance that contains covalent bonds?
A molecular formula represents a substance that contains covalent bonds. This formula shows the types and numbers of atoms present in a molecule, such as H2O for water, which consists of covalent bonds between hydrogen and oxygen atoms.
What substance only contains more then one type of atom chemically joined together?
A compound is a substance that contains multiple types of atoms chemically bonded together. Examples include water (H2O) and carbon dioxide (CO2).
What is a substance we drink that contains no organic compound?
Water is a common example of a substance that we drink that contains no organic compounds. It is a simple chemical compound composed of hydrogen and oxygen atoms.
Which substance contain more hydrogen atoms per molecule ammonia or water?
Ammonia; it contains three hydrogen atoms per molecule, while water has two.
Is Mineral water pure substance or mixture?
No. A pure substance describes one that contains only one type of element/molecule. Mineral water is a mixture, since it contains many different types of minerals, next to water, and can therefore not be called a "pure" substance.
What substance contains all type of atoms found in minerals?
Rocks and minerals are made up of various types of atoms such as silicon, oxygen, aluminum, iron, calcium, and others. These atoms are naturally occurring elements that form different combinations and structures to create the wide variety of minerals found in nature.
Is icy water both pure and contains different types of atoms?
All water contains two different types of atoms: hydrogen and oxygen, twice as much hydrogen as oxygen. If its pure water that's all there is in it. The purity of the water has nothing whatsoever to do with its temperature: pure water can be boiling hot, and icy water can be filled with impurities.
Is mineral water a pure water?
No. A pure substance describes one that contains only one type of element/molecule. Mineral water is a mixture, since it contains many different types of minerals, next to water, and can therefore not be called a "pure" substance.
What is a pure substance that contains three elements that are chemically bond?
One example of a pure substance containing three elements that are chemically bonded is water (H2O). Water is composed of hydrogen and oxygen atoms that are chemically bonded to form the water molecule.
How many Atoms are in one molecule of the substance?
The number of atoms in one molecule of a substance depends on its chemical formula. For example, a water molecule (H₂O) contains three atoms—two hydrogen atoms and one oxygen atom. In contrast, a glucose molecule (C₆H₁₂O₆) contains 24 atoms—six carbon, twelve hydrogen, and six oxygen atoms. Therefore, to determine the exact number of atoms in a molecule, one must refer to the specific chemical formula of that substance.
What substance contains two or more different kinds of atoms bonded together?
A compound contains two or more different kinds of atoms bonded together. Examples include water (H2O) and carbon dioxide (CO2).
Is pure water monatomic molecular or lattice?
Pure water is a molecular substance composed of H2O molecules. It is not monatomic because it contains two different types of atoms (hydrogen and oxygen) bonded together. It does not form a lattice structure like in ionic compounds.
