Ionic Bonding

Question 0

What elements does ionic bonding occur with?

Answer 0

occurs between metals and non metals

Question 1

Why does chemical bonding occur?

Answer 1

To obtain full outer shell & noble gas configuration

Question 2

What happens in ionic bonding?

Answer 2

Electrons are transferred from metals to non-metal forming positive and negative ions held by strong forces of electrostatic attraction

Question 3

Ionic Bonded compound properties:

Answer 3

• solid at room temp
• very high melting & boiling points
• conduct electricity when molten/dissolved in polar substance

Question 4

Why can’t ionic compounds conduct electricity when solid?

Answer 4

The ions are not free to move to carry current

Question 5

Why are ionic compounds soluble?

Answer 5

Polar molecules have delta +ve & delta -ve charges which interact with the negative ions and positive ions respectively which causes the ions to breakfree

Question 6

If delta +ve & delta -ve charges are weaker than electrostatic forces, why do do they cause ionic compounds to dissolve?

Answer 6

Because there are many delta +ve and delta -ve charges that collectively pulling the ionic compound apart.
