What are ions |
Ions are charged particles they can be single atoms or groups of atoms |
|
|

To become stable |
|
|
What happens when metals form ions |
They lose electrons from their outer shell to form positive ions |
|
|
What happens when non metals form ions |
They gain electrons into their outer shell to form negative ions |
|

|
Why do elements in the same group form ions with the same charge |
They all have same number of outer electrons so they lose or gain the same number to get an outer shell |
