Electrons, bonding and structure

Question 1

ionic bonding

Answer 1

• Electrons are transferred from the metal atom to non-metal atom.
• oppositely charged ions are formed, bonded together by electrostatic attraction.

Question 2

giant ionic lattice

Answer 2

• Each ion is surrounded by oppositely charged ions

- ions attract each other

Question 3

properties of ionic compounds

Answer 3

• High melting & boiling point, large amount of energy needed to break the bonds
• this is due to electrostatic forces between oppositely charged ions.

Question 4

ionic compounds conductivity

Answer 4

• solid ionic compound does not conduct electricity

- when melted or dissolved however they can conduct electricity as the ions are free to move around.

Question 5

what do ionic compounds dissolve in?

Answer 5

polar compounds
