Study Notes

Ionic Bonds and Ionic Compounds

Ionic bonds are formed between metals and nonmetals through the transfer of electrons.
Metals lose electrons to form positively charged cations.
Nonmetals gain electrons to form negatively charged anions.
Binary ionic compounds are composed of two elements, a metallic cation and a nonmetallic anion.

Determining the Charge of Ions

The group number of an element in the periodic table dictates its charge.
Group 1 elements have a +1 charge.
Group 2 elements have a +2 charge.
Group 13 elements have a +3 charge.
Group 16 elements have a -2 charge.
Group 17 elements have a -1 charge.

Crystal Lattice and Properties of Ionic Compounds

Ionic compounds form a crystal lattice structure, where positive and negative ions are arranged in a three-dimensional pattern.
The strong electrostatic attractions between oppositely charged ions in a crystal lattice result in:
- High melting and boiling points due to the large amount of energy required to break the bonds.
- Poor electrical conductivity in the solid state, as electrons are tightly held and cannot move freely.
- Good electrical conductivity when dissolved in water or molten, as the freely moving ions can carry electric charge.

Energy and the Ionic Bond

Lattice energy is the energy required to separate one mole of ions from its crystal lattice.
A higher lattice energy indicates a stronger ionic bond.
