Ionic Versus Covalent

Ionic Bonding Versus Covalent Bonding

What is Covalent?

What's the difference between them?

Ionic Compounds

• We have been learning how to create ionic compounds such as NaBr and MgCl₂

• We also learned how to name ionic compounds like sodium bromide and magnesium chloride. 

  
  

• But there are more than ionic compounds in the chemistry world.  One other example of chemical bonding is called covalent compounds.

What is Covalent Bonding?

Covalent Bonding occurs between 2 nonmetals. The electrons between them are shared.

Multiple Choice

What table are nonmetals found in the periodic table?

• The left side that is yellow

• The middle that is purple

• The right side that is green.

Properties of Covalent Bonding

• They have a low melting point

• They have a low boiling point

• They can be found as solids, liquids or gases.

• They do NOT conduct electricity.

• These compounds CANNOT be dissolved in water.

Multiple Choice

Covalent bonds can be found as _______?

• only solids

• solids and liquids

• solids, liquids and gases

Multiple Choice

What is a property of covalent bonds?

• They are pretty

• They have a LOW melting point

• They can dissolve in water

Multiple Choice

What is a property of covalent bonds?

• They cannot be dissolved in water.

• They have a high melting point

• They are orange

Properties of Covalent Compounds are the opposite of Ionic Compounds

Properties of Ionic Bonding

• They have a high melting point

• They have a high boiling point

• They are usually solids.

• They DO conduct electricity.

• These compounds CAN be dissolved in water.
