Lattice energy holds together what bond?
ionic bonds
What is Lattice energy?
the energy required to completely separate an ionic compound’s cations and anions
The larger the charges on ions, the larger the ____ energy?
bigger charges = larger lattice energy
shorter bond distances (smaller ions), the larger?
shorter bond distances = larger lattice energy
Lattice energy equation
Lattice energy = (cation charge * anion charge) / bond distance
in general, an atoms size gets smaller as you move what direction across the periodic table?
to the right and up (the same trend as electronegativity -makes sense bc the shorter or smaller a bond, the stronger its energy for an e-)
How is Latice energy (LE) is related to Size (S) and Charge (C)?
• *LE and C directly, both increase or decrease * * LE and S indirectly, LE increases as size decreases or vice versa
