What is Atom and Molecule? Atoms and molecules are an important part of science and the building blocks of matter. Understanding them is the foundation for understanding all branches of science.

For example, we've got water. Water is a compound of hydrogen and oxygen. The chemical name for water is H₂O because each of its molecules contain two hydrogen atoms and one oxygen atom.

Atoms and molecules make up the three common states of matter on ... Ask students questions such as the following to guide their thinking: What are some examples of matter? Tell students that matter ...

For example, you have to stay in the classroom ... and watching how it bends can show the location of atoms in a molecule. So what do molecules look like? They are a grouping of atoms, with ...

For example, the red sphere for oxygen could represent a tank of oxygen. Linus collects atoms to make molecules. In the real world, chemists don’t take single atoms and put them together to make ...

It highlights everyday examples of chemical changes, such as burning wood and the digestion of food. The film illustrates how molecules and atoms interact during these changes, using examples like ...

Physicists are increasingly using ultracold molecules to study quantum states of matter. Many researchers contend that molecules have advantages over other alternatives, such as trapped ions, atoms or ...

The distinct colors of airglow are the result of atoms and molecules releasing particular amounts of energy (quanta) in the form of light. For example, at high altitudes ultraviolet light can spli ...
