Ionic Bonding

Question 1

What happens with electrons in an Ionic Bond?

Answer 1

Electrons are transferred between two atoms:

• Shared electrons are transferred to atom with highest electronegativity
• VERY unequal sharing

Question 2

What types of atoms does Ionic bonding occur between?

Answer 2

Metals and Nonmetals (cations and anions)

Question 3

What causes Cations and Anions to form Ionic bonds?

Answer 3

Their opposite charges (opposites attract)

Question 4

What force holds Ionic Compounds together?

Answer 4

Electrostatic Forces (Electrostatic Attraction)

Question 5

What term is used for ionic compounds (instead of “molecule”)?

Answer 5

Formula Unit

Question 6

What is the form of Ionic Compounds at room temperature?

Answer 6

Crystalline Solid (Crystal Lattice)

(a crystal lattice occurs when Ions are packed together)

Question 7

What is the Melting Point and Malleability of Ionic Compounds?

Answer 7

• High Melting Points
• Low Malleability

(This is due to the strength of Ionic Bonds/Compounds)

Question 8

Can Ionic Bonds conduct electricity?

Answer 8

Yes - when dissociated in water or melted

Question 9

What happens when Ionic Compounds dissolve in water? What is this process called?

Answer 9

• Electrostatic forces reduce (bonds break up)
• This process is known as dissociation (or solvation)

(when Ionic bonds break up, electrons become more delocalized)

Question 10

If you see this card, practice drawing a complete Lewis dot structure for a random ionic compound

Answer 10

Do it :)
