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.

These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size and colour that are joined together. This particle diagram represents ...

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

Catalysts facilitate crucial chemical reactions in nature and industry alike. In a subset of them, catalytic activity is ...

By exerting unprecedented control over extremely cold atoms, researchers have put them in a state with several simultaneously ...

MIT physicists have captured the first images of individual atoms freely interacting in space— “free-range” particles never ...

Scientists have just snapped pictures of single atoms as they move around freely, capturing details once hidden from sight.

A quantum computer has used a single atom to model the complex dynamics of organic molecules interacting with light ...

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.

Students will record their observations and answer questions about the activity on the activity sheet. The Explain It with Atoms and Molecules and Take It Further sections of the activity sheet will ...
