Question 1

Ionic bonding is…

Answer 1

The transferring of electrons - loosing or gaining electrons

Question 2

Ionic compounds have a regular ________ _______ this is

Answer 2

•ionic
•structure
This is the closely packed ion arrangement and it’s very compact because the opposite - and + ions are attracted to one another.

Question 3

Ionic compounds all have similar properties such as (3)

Answer 3

• high melting points
• high boiling points
• dissolve easily because the ions separate and are free to

Question 4

Groups __ and ___ and ___ and ____ are the most likely to form ions

Answer 4

1 and 2

6 and 7

Question 5

The overall charge of any compound is…

Answer 5

0

Question 6

Look at charges to work out the formula of an ionic compound e.g

Answer 6

Magnesium chloride contains mg2+ and Cl-
We need 2 Cl to balance out the magnesium and therefore the formula is MgCl2 because we need 2 chloride and 1 magnesium to balance it

Question 7
