Ionic Compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. It typically consists of a metal and a non-metal.

Define lattice energy in the context of ionic compounds.

Back

Lattice energy is the amount of energy required to separate one mole of the ions of an ionic compound. It is influenced by the size of the ions and their charges.

What is the formula for Calcium Nitrate?

Back

The formula for Calcium Nitrate is Ca(NO3)2.

Front

Which compound has the lowest lattice energy: RbI, NaCl, or MgO?

Back

RbI has the lowest lattice energy among the given compounds.

Front

Which compound would have the highest lattice energy: NaCl, KBr, or AlPO4?

Back

AlPO4 would have the highest lattice energy due to the high charge density of Al^3+ and PO4^3- ions.

Front

What factors affect lattice energy?

Back

Lattice energy is affected by the size of the ions and the charges of the ions involved in the ionic bond.

Front

Explain why smaller ions typically result in higher lattice energy.

Back

Smaller ions can get closer together, leading to stronger electrostatic attractions, which increases the lattice energy.

Front

What is the significance of lattice energy in ionic compounds?

Back

Lattice energy is significant because it influences the stability, solubility, and melting points of ionic compounds.

Front

How does the charge of ions affect lattice energy?

Back

Higher charges on ions result in stronger electrostatic attractions, leading to higher lattice energy.
