Guided Notes

10 min

Key concepts students will learn:

  • Every crystal's atoms are arranged in a highly organized, repeating pattern, which is the defining feature of a crystal.

  • Each crystalline material’s atomic arrangement falls into one of six different families: cubic, tetragonal, orthorhombic, monoclinic, triclinic, and hexagonal.

  • Environmental conditions like pressure, temperature, and chemical environment can influence which geometric shape a crystal grows into.
