Crystal Lattice
Definition
A crystal lattice is a symmetrical, three-dimensional arrangement of atoms or ions in a crystal. It's the repeating pattern of particles that forms the solid structure of a crystal.
Analogy
Think of a crystal lattice like an infinitely expanding LEGO structure. Each piece (or atom/ion) has its own specific place and they all fit together perfectly to create the overall structure. Just as you can predict where each LEGO brick will be based on the pattern, you can predict where each atom or ion will be in a crystal lattice.
Related terms
Lattice Energy: This is the energy required to break apart an ionic compound and convert its component atoms into gaseous ions. It's like how much effort it would take to dismantle your LEGO structure into individual bricks.
Unit Cell: This is the smallest repeating unit in a crystal lattice that shows the entire pattern of atoms. It's like identifying one small section of your LEGO structure that, if repeated, could recreate the whole thing.
Ionic Bonding: This refers to when positively charged ions (cations) and negatively charged ions (anions) are attracted to each other and form bonds. Like magnets with opposite poles attracting each other.
