Compuesto iónico

Ionic compounds are formed from metallic and non-metallic elements, such as sodium chloride. Unlike covalent compounds, ionic compounds form large, ordered crystalline solids with ions in a lattice structure. They are characterized by being hard, brittle, and having high melting and boiling points.

What is a typical example of an ionic compound?

• Carbon dioxide

• Sodium chloride

• Methane

• Water

How do ionic compounds differ from covalently bonded compounds in terms of structure?

• They form separate molecules.

• They have no definite structure.

• They form large ordered crystalline solids.

• They are always gaseous.

What is the arrangement of ions in ionic compounds?

• Randomly scattered

• In a gaseous form

• In a liquid form

• In a lattice structure

Which of the following is a characteristic of ionic compounds?

• Low melting points

• Poor electrical conductors

• High boiling points

• Soft and flexible

What physical property is common in ionic compounds?

• They are soft and flexible.

• They are hard and brittle.

• They are ductile.

• They are malleable.
