Giant Ionic lattice

Question 5

Describe the Sodium Chloride Bonding

Answer 5

Electrostatic force between Na+ and Cl-

Question 6

Why does Iodine have a low melting point

Answer 6

the weak intermolecular force between simple molecules which need little energy to break

Question 7

Is this Covalent or Ionic
____________
/ H X o X H \
\___ X x X____/

Answer 7

Covalent

Question 8

Describe and explain the Melting of a Giant Metallic substance. 3

Answer 8

High MPT
Stri=ong electrostatic force of attraction between positive metal Ions and delocalised electrons
Which needs a lot of energy to break

Question 9

Describe the Giant Ionic substance’s Melting point.
3

Answer 9

HMP
Because of a strong electrostatic force between the positively charged metal and negatively changed non-metal
Which requires a lot of force to break
