Lattices in ionic crystals
- A lattice is like the architectural blueprint of an ionic crystal. Imagine a skyscraper, with its floors, offices, and rooms all laid out in a predictable pattern. Similarly, a lattice is a three-dimensional grid where ions hold a meetup party, keeping an orderly arrangement that continues indefinitely.
- The arrangement of the ions is like guests at a party – they depend on their size (think tall and short guests) and charge (imagine guests wearing red and blue, representing positive and negative charge).
Empirical formula of ionic compounds
- Ionic compounds give out their identity card as an empirical formula. This tells us the simplest ratio of the different types of ions in the structure.
- For instance, sodium chloride (NaCl) says it's a 1:1 party – for every sodium ion (Na+), there's a chlorine ion (Cl-) rocking out. Even if you are looking at a single grain of salt, which can host a quadrillion ions, the 1:1 ratio remains the same.
