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.

Physicists have used a novel technique to observe individual atoms interacting in free space for the first time ever. The new technique confirms a century-old quantum mechanical theory.

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 ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy ...

(A) The plasma membrane of a cell is a bilayer of glycerophospholipid molecules. (B ... phosphatidylcholine is shown as an example. The hydrophilic head is composed of a choline structure ...
