Ionic Compound: These are compounds composed of ions, charged particles that form when an atom gains or loses electrons. In our analogy, these are the individual lego blocks.
Ionization Energy: This is the energy required to remove an electron from a neutral atom. It's like trying to take a tiny piece off one of your lego blocks.
Electron Affinity: This is the amount of energy released when an electron is added to a neutral atom. It's like if adding another small piece onto your lego block made it suddenly become more stable and release energy.
