Bonding and structure

Question 1

What are the 4 different types of bonding?

Answer 1

Ionic bonding
Metallic bonding
(Simple) covalent
Giant covalent

Question 2

What is ionic bonding?

Answer 2

Ionic bonding is the strong electrostatic attraction between positive and negative ions.
eg: Na+ and Cl- forming NaCl

Question 3

How is an ionic compound arranged?

Answer 3

Regular lattice structure

Question 4

Describe the melting/boiling points of ionic compounds

Answer 4

Ionic bonding involves strong electrostatic forces. This causes a high melting/ boiling point in ionic compounds

Question 5

How are melting/boiling points determined?

Answer 5

To melt or boil the structure, the forces holding the structure together have to be overcome. Therefore a lot of thermal of energy is required if the bond is strong.

Question 6

Describe conductivity in a structure

Answer 6

For a structure to be conductive of heat or electricity, there should be charged particles within the structure (electrons or ions) that can move to carry the charge along

Question 7

Do ionic compounds conduct heat or electricity as solids?

Answer 7

No mobile ions or electrons can be found in this structure => not conductive in the solid state
