Atoms

9 Splashes.

1. Electron OrbitalAn electron does not circle the center of an atom like a planet.
2. AtomEverything around you is made of atoms.
3. MoleculeA molecule is a group of atoms held together by chemical bonds.
4. ProteinProteins are the tiny machines of living things.
5. Crystal LatticeIn a crystal, atoms are lined up in a pattern that repeats over and over, like tiles on a floor.
6. Unit CellsA crystal is one small box of atoms, its unit cell, repeated in every direction.
7. Orbital AtlasAn orbital is a wave that tells where an electron in an atom is likely to be.
8. Molecule ViewerScientists share the 3D shapes of molecules as files of atom positions: proteins and DNA in the Protein Data Bank, small molecules as SDF, MOL or XYZ files.
9. Periodic TableEvery element as a real sample: lumps of metal, crystals, liquids and glowing gases in sealed glass.
