Q

A
Where reduction and oxidation both occur
2
Q
What is a cation?
A
Ions lose electrons and become positively charged
3
Q
What is an anion?
A
Ions gains electrons and becomes negatively charged
4
Q
What is ionic bonding?
A
The electrostatic attraction between oppositely charged ions
5
Q
What are the ionic properties?
A
High MP/BP
- Giant ionic lattice made up of lots of ionic bonds
- Ionic bonds are very strong so lots of energy is needed to break bonds
Conducts electricity as liquid
- Ions move freely = high conductivity
