This ionic crystal lattice is most likely that of formula

• MgS

• K₃N

• MgCl₂

• Na₂O

Answer explanation

There is a 1:1 ratio of cations to anions, therefore it is MgS. The other solids have a different ratio of cations to anions.

Identify the following structure as an Ionic solid or other.

• Ionic

• Other

Answer explanation

These particles are all the same therefore it cannot be ionic since you would need 2 different looking ions.

This ionic crystal lattice is most likely that of formula

• NaCl

• MgO

• Li₂S

• AlF₃

Answer explanation

There is a 2:1 or 2:1 ratio of ions, the other substances have a different ratio.

Identify the following structure as an Ionic solid or other.

• Ionic

• Other

Answer explanation

These particles are not arranged in a regular way. These particles are not ions, they are molecules.
