Ionic Compounds

Front

What is the resulting formula when Na⁺¹ and Cl^-1 combine?

Back

NaCl

Front

Define a crystal lattice in the context of ionic compounds.

Back

A three-dimensional geometric arrangement of particles where each positive ion is surrounded by negative ions and vice versa; varies in shape due to sizes and relative numbers of the ions bonded.

Front

What is the name of the compound with the formula Fe₂O₃?

Back

Iron (III) oxide.

Front

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

Back

RbI.

Front

Write the formula for Calcium Nitrate.

Back

Ca(NO₃)₂.

Front

What is lattice energy?

Back

The energy required to separate one mole of an ionic solid into its gaseous ions.

Front

What factors affect lattice energy?

Back

The charge of the ions and the distance between them (ionic radii).

Front

What is the significance of the octet rule in ionic bonding?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.

Front

How do you determine the charge of a transition metal in an ionic compound?

Back

By using the known charges of the other ions in the compound and balancing the overall charge.

Front

What is the difference between a cation and an anion?

Back

A cation is a positively charged ion, while an anion is a negatively charged ion.
