?
What is an ion?
Ions are electrically charged particles formed when atoms lose or gain electrons.
1 of 11
Ionic bonding occurs between...?
Metals and non metals
2 of 11
Metal atoms...?
Lose electrons and become positive ions
3 of 11
Non metal atoms...?
Gain electrons and become negative ions
4 of 11
Can ionic compounds conduct electricity?
Only if molten or dissolved in water so the ions can carry the current
5 of 11
How does lithium react with water?
Just floats on water and fizzes gently
6 of 11
How does potassium react with water?
Bursts into flame, zooms across the water and spits
7 of 11
How does caesium react with water?
Explodes on contact with water
8 of 11
What are group 1 metals known as?
Alkali metals
9 of 11
Why do ionic compounds have high melting and boiling points?
Because of the strong electrostatic forces between the ions, it takes a great deal of energy to seperate the negative and positive ions.
10 of 11
Why don't solid ionic compounds conduct electricity?
The ions are held firmly in place and cannot move to carry the current.
