Question 1

Describe the structure of ionic compounds

Answer 1

Giant ionic 3D lattice

Question 2

Ionic compound bonding?

Answer 2

An ELECTROSTATIC FORCE OF ATTRACTION between the oppositely charged ions

Question 3

Why are ionic compounds hard

Answer 3

They consist of a REGULAR PATTERN of oppositely charged ions with STRONG BONDS between them

Question 4

Why are ionic compounds brittle?

Answer 4

After a sharp blow the like charged ions will come into contact with eachother and repel eachother, and the structure will fall apart

Question 5

Why do ionic compounds have a high melting point?

Answer 5

It takes a lot of energy to break the STONG ELECTROSTATIC FORCES OF ATTRACTION between the oPPOSITELY CHARGED IONS

it also has a GIANT STRUCTURE

Question 6

Why are ionic compounds soluble in water?

Answer 6

The water molecules are able to break down the IONIC BONDS BETWEEN THE OPPOSITELY CHARGED IONS

Question 7

when do ionic compounds conduct electricity?

Answer 7

When they’re molten / aqueous

Question 8

Why do solid ionic compounds not conduct electricity ?

Answer 8

This ions aren’t free to move to the electrodes as they’re held together by STRONG ELECTROSTATIC FORCES OF ATTRACTION

Question 9

what are 3 examples of macromolecules?

Answer 9

Diamond
Graphite
Sand??

Question 10

Describe the structure of diamond

Answer 10

The Strong Covelant bonds for a GIANT 3-D TETRAHEDRAL LATTICE
