When atoms of different types of elements join together, they make molecules called compounds. Water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. This is why it's called H 2 O. Water will always have 2 times the number of hydrogen atoms as oxygen atoms.
A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms . This produces two hydrogen atoms and one oxygen atom. But these atoms alone do not have the properties of water.
Every drop of water contains millions of identical water molecules. Rust lattice. Rust is made out of a lattice of iron and oxygen atoms. A lattice is a web of atoms that are connected together. Each atom is bonded to the neighboring atoms in the lattice. Salt lattice Salt is made up of a lattice of sodium and chlorine particles. ...
Science >> Chemistry for Kids Water is one of the most important substances on planet Earth. All forms of life need water to live. Water is constantly moving about the Earth through the water cycle. What is water? Like all "stuff", water is made up of molecules. Maybe you have heard water called H 2 O? This is actually the chemical formula for ...
Oil molecules try to connect to water, but hydrogen bonds connecting water molecules together remain too strong to let them in. If pulled across the surface of water, oil will stretch out to a layer the thickness of one molecule since each oil molecule attempts to attach itself to water.

Water (H 2 O, HOH) covers 70-75% of the Earth's surface in its liquid and solid states, and is present in the atmosphere as a vapor.It is the most abundant molecule on the Earth's surface.. At room temperature, it is a nearly colorless, flavorless, and odorless liquid. Many substances dissolve in water and it is commonly seen as the universal solvent; because of this, water in nature and i...
Surface Tension. The top layer of water acts like an elastic or stretchy sheet. This is called surface tension, and it happens because of the attraction between molecules, or the sticky nature of ...
