What is a melting point for ionic bonds
Questions about the structure and properties of ionic compounds
1. What is the result of the brittleness of ionic compounds?
The forces of attraction and repulsion of the ions act in all directions. If layers of the same ions come together under pressure, the ions repel each other.
2. Why do ionic compounds have high melting and boiling points?
Ionic compounds have high melting and boiling points because of the strong forces of attraction between the ions. Separating the ions from one another requires a large amount of thermal energy.
3. What happens to the ion lattice at the melting point of the ion compound?
The lattice collapses at the melting point of the ionic compounds, and depending on the temperature, the ions only form loose conglomerates.
4. Why do the melting points decrease in the order KCl, KBr, KI?
Due to the increasing ionic radii of the halide ions in the series chloride - bromide - iodide, the distance between the centers of charge of the ions increases and thus the force of attraction decreases.
5. Why do the melting points decrease in the order NaI to KI?
Due to the increasing radius of the alkali metal, the distance between the centers of charge of the ions increases and thus the force of attraction decreases.
6. Why do the alkaline earth metal oxides have particularly high melting points?
The alkaline earth metal oxides have particularly high melting points primarily because of the double charge of the ions.
7. Why do sodium and chlorine react exothermically with one another?
Because the ionic compound NaCl is lower in energy than the starting elements. The lattice energy released ensures that the entire process takes place as an exothermic reaction.
8. Which energies have to be expended or are released during the formation of NaCl?
Energies or enthalpies to be expended:
Enthalpy of sublimation for Na atoms
Enthalpy of dissociation for chlorine molecules
Ionization energy for Na atoms
Liberated energies or enthalpies:
Enthalpy of reaction
9. What is lattice energy?
Lattice energy is the energy that is released or has to be expended when a solid crystalline lattice is formed from gaseous ions.
