Understanding the Brittleness of Ionic Compounds

The video explains why ionic compounds are brittle, using sodium chloride as an example. It describes how applying force causes ion layers to shift, bringing like charges closer and creating repulsion, which leads to the compound breaking.

What characteristic of ionic compounds is highlighted in the introduction?

• They are conductive.

• They are brittle.

• They are malleable.

• They are flexible.

Which compound is used as an example to explain the brittleness of ionic compounds?

• Potassium bromide

• Sodium chloride

• Magnesium oxide

• Calcium carbonate

What happens when force is applied to an ionic compound like sodium chloride?

• The compound melts.

• The compound becomes more conductive.

• The ions shift and create repulsion.

• The ions become more tightly packed.

What causes the breakage in ionic compounds when force is applied?

• Repulsion between like charges

• Attraction between opposite charges

• Formation of new bonds

• Increase in temperature

Why do like charges in ionic compounds create repulsion when they come closer?

• Because they attract each other

• Because they have different charges

• Because they have the same charge

• Because they are neutral
