Ionic Compounds

Question 1

Compound

Answer 1

2 or more elements chemically combined.

Question 2

Ionic Compounds

Answer 2

Made up of negative and positive ions that have resulted from the transfer of electrons from a metal to a non metal. Valence electrons are lost or gained to form a full octet.

Question 3

Electrolytes

Answer 3

Substances that will dissolve in water and conduct electricity.

Question 4

How do Ionic compounds form solutions that will conduct electricity?

Answer 4

Ionic compounds form solutions that will conduct electricity because they are made up of charged ions. The compounds dissolve and the ions separate from each other.

Question 5

How are ionic compound held together?

Answer 5

Ions in ionic compounds are held together by the electrostatic force between oppositely charged
bodies. In other words, positive and negative ions attract.

Question 6

Ions

Answer 6

An atom with an overall charge. To become stable, atoms lose or gain electrons to fill their valence shells.

Question 7

What are the two types of ions?

Answer 7

Cations- positively charged

Antions- negatively charged

Question 8

Characteristics of Ionic Compounds

Answer 8

contain a metal & non-metal.
• Metal LOSES electrons, non-metal TAKES electrons.
• A strong ionic bond forms.
• Conduct electricity when melted or dissolved.
• High melting point.
• Hard and Brittle.
