Ionic bonding + Properties of Ionic compounds

Question 1

What is ionic bonding?

Answer 1

When metals give their outer electrons to non-metals to get a full outer-shell, producing charged ions

Question 2

What do metals and non-metals become in this ionic bonding?

Answer 2

Metals become positive ions (cations) and non-metals become negative ions (anions).

Question 3

Why do ionic compounds (giant lattice structure) have high melting and boiling points?

Answer 3

• In giant ionic lattices there is a strong attraction between the positive and negative ions.
• This takes a lot of energy to overcome.
• Therefore, ionic compounds are solid at room temp

Question 4

What are properties of Giant Ionic Lattice properties?

Answer 4

• Solid ionic compounds cannot conduct electricity, as the ions cannot move.
• When they are melted or dissolved in water, the ions are able to move around.
• The ions carry charge so ionic liquids can conduct electricity.
