What are bonds that tend to be crystalline solids with high melting points?
Bonds that tend to be crystalline solids with high melting points are the lattice energy of the compound.
Lattice energy is the amount of energy given off when positive and negative ions in the gaseous state combine to form a crystal of the compound in an exothermic reaction.
The lattice energy for a compound will be smaller if the ions or the elements in the compound are larger, and if the ionic charge is relatively small.
The force of attraction between ions is given by:
