Is water an element or compound

Water is everywhere on our planet and it's the reason we have organic life. It shapes our mountains, carves our oceans, and drives our weather.

Byju's Answer. Is water an element or a compound? Give reason in support of your answer. Open in App. Element: An element is composed of the same atoms that is, each atom has the same number of protons in its nucleus as all other atoms of that element..

Is water an element or compound

Water is important for life, weather, and many processes. Scientists classify water as a compound and not an element. An element is a substance composed of a single type of atom. Hydrogen element symbol H and oxygen element symbol O are examples of elements. So, water is made from elements, but is not itself an element. Before people knew about atoms and molecules , water was considered to be an element. Some traditional practices still consider water to be an element, but this is different from the scientific definition. When two atoms form a chemical bond, they make a molecule. Hydrogen and oxygen are both elements, but they also normally exist as molecules consisting of two atoms H 2 and O 2. Because hydrogen forms bonds with oxygen to make water, water is a molecule. Water is also a compound. A molecule is made whenever two or more atoms form chemical bonds, while a compound occurs whenever two or more different atoms form chemical bonds.

In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. Water is also a compound.

Is water an element or compound

When we speak of a pure substance , we are speaking of something that contains only one kind of matter. This can either be one single element or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties. Compounds are made up of one or more element. If we take two or more pure substances and mix them together, we refer to this as a mixture. Mixtures can always be separated again into component pure substances, because bonding among the atoms of the constituent substances does not occur in a mixture. Whereas a compound may have very different properties from the elements that compose it, in mixtures the substances keep their individual properties. For example sodium is a soft shiny metal and chlorine is a pungent green gas.

Use limited data to select advertising. Also, some molecules contain both ionic and covalent bonds between the various atoms. What Is a Covalent Bond in Chemistry? By this definition, water is both a molecule and a compound. Learn about our Editorial Process. Because hydrogen forms bonds with oxygen to make water, water is a molecule. Water is important for life, weather, and many processes. Helmenstine holds a Ph.

Water is everywhere on our planet and it's the reason we have organic life. It shapes our mountains, carves our oceans, and drives our weather. It would be logical to think that water must be one of the basic elements.

The compounds can be broken down into constituent particles chemically only. Some traditional practices still consider water to be an element, but this is different from the scientific definition. By this definition, water is both a molecule and a compound. Here are a few of its eccentricities:. Under this narrow definition, oxygen and hydrogen are molecules but not compounds. A compound forms whenever two or more atoms form chemical bonds with each other. Scientists classify water as a compound and not an element. Anne Marie Helmenstine, Ph. Before mankind knew about atoms and molecules, water was considered an element. The thinking is that since water consists of a combination of hydrogen and oxygen atoms, it must be a mixture. If you release gas from hydrogen cylinder and oxygen cylinders into a space, you get a mixture of hydrogen and oxygen molecules. Use profiles to select personalised advertising.
