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. It would be logical to think that water must be one of the basic elements. But in reality, water is a chemical compound.

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.. An element has fixed melting and boiling points. Compound: A compound is a substance that results from a combination of two or more different chemical elements.

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. Under this narrow definition, oxygen and hydrogen are molecules but not compounds. Water is both a molecule and a compound.

Because hydrogen forms bonds with oxygen to make water, water is a molecule. Create profiles to personalise content.

Water is the most abundant molecule on the Earth's surface and one of the most important molecules to study in chemistry. The facts of water chemistry reveal why this is such an incredible molecule. Water is a chemical compound. Each molecule of water, H 2 O or HOH, consists of two atoms of hydrogen bonded to one atom of oxygen. There are several important properties of water that distinguish it from other molecules and make it the key compound for life:. Use limited data to select advertising.

Is water an element or compound

Matter is anything that has mass and volume. Nearly everything within the known universe, from water, to a fish, to the planets, is composed of matter. It may seem beneficial to have one vocabulary term to describe every substance that exists. However, each of these "things" has its own distinct characteristics and, therefore, can be classified using more specific terminology. Matter can be classified as either a pure substance or a mixture, based on its composition. A pure substance is a form of matter that has a definite composition. Furthermore, the physical properties, such as color, shine, density, and melting point, of a pure substance must be consistent throughout the entire sample. Pure substances can be categorized as either elements or compounds.

She has taught science courses at the high school, college, and graduate levels. Hydrogen element symbol H and oxygen element symbol O are examples of elements. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier. Water is a pure substance and not a mixture. Learn about our Editorial Process. A glass of ice water put in an air tight container 1 after a short while, state whether the air tight container will contain less water vapour or more water vapour 2 give reason to support your answer. 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..

Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition meaning that it is the same everywhere and properties that are constant throughout the sample meaning that there is only one set of properties such as melting point, color, boiling point, etc. A material composed of two or more substances is a mixture.

Give reasons in support of your answer. Scientists classify water as a compound and not an element. Pure Substances. Covalent or Molecular Compound Properties. Water consists of two types of atoms: hydrogen and oxygen. Standard VI Chemistry. Use profiles to select personalised advertising. Understand audiences through statistics or combinations of data from different sources. Give three reasons for your answer. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. Develop and improve services. These unusual properties have had a profound impact on the development of life on Earth and on the weathering and erosion of Earth's surface. So, water is made from elements, but is not itself an element. Measure content performance. Create profiles to personalise content.
