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.
