What are Ions ?
Ions are electrically charged particles formed when atoms lose or gain electrons
1 of 8
What do metal atoms form?
positive ions- they lose an electron
2 of 8
What do non metal ions form?
negative ions- they gain an electron
3 of 8
What are ionic bonds?
The strong electostatic attraction between oppostitely charged ions
4 of 8
How can you work out the charge on a metal ion?
the number of ions formed by a metal is equal to the group number of the metal
5 of 8
How can you work out the charge on a non metal ion?
The number of charges on an ion formed by a non metal ion is equal to the group number minus eight
6 of 8
What is ionic bonding?
ionic bonding is when metals react with non metals, electrons are transferred from the atoms to the non metal atoms, forming ions.
