1
Q

How are ionic compounds formed?

A

When a metal forms a positive ion and reacts with a non-metal negative ion because opposite charges attract.

2
Q

What holds these ions together?

A

Very strong forces of attraction between the opposite charges. This is called electrostatic forces of attraction.

3
Q

How do they bond?

A

The metals lose electron(s) and the non metals gain electron(s).

4
Q

What type of ions does group one form?

A

+1 ions

5
Q

What type of ions does group two form?

A

+2 ion

6
Q

What type of ions does group three form?

A

3+ ions if they form ions instead of sharing them.

7
Q

What type of ions does group four form?

A

They do not form ions except for lead and tin.

8
Q

What type of ions does group five form?

A

-3 ions if making ions instead of sharing electrons

9
Q

What type of ions does group six form?

A

-2 ions if they form ions instead of sharing electrons

10
Q

What type of ions does group seven form?

A

-1 ions if they form ions instead of sharing electrons

11
Q

What type of ions does group zero form?

A

Never form any ion compounds

12
Q

How can ionic bonding be shown as a diagram?

A

A dot and cross diagram showing their ions in their own square brackets

13
Q

Why do ionic compounds have high melting and boiling points?

A

Because it is hard to separate the ions as you have to overcome all of the electrostatic forces of attraction acting in all directions.

14
Q

When will ionic solid melts?

A

When there is enough energy to separate the ions.

15
Q

Why can a solid ionic compound not conduct electricity?

A

Because the ions are in a fixed position not being moved around and that is why ionic liquids can conduct electricity because they have ions that are free to move.
