Question

is water an compound or element ​

Answer 1

Answer:

Water is a compound because it is composed from two hydrogen atom and one oxygen atom. Water is considered a compound because it is made up of more than one element. By definition, a compound is composed of multiple atoms from different elements. Water has 2 hydrogens and 1 oxygen.

Answer 2

Answer:

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.

Compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.

Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that a molecule consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. However, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier.

Also, some molecules contain both ionic and covalent bonds between the various atoms.

In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds.
