A
Oxidation
2
Q
What charge does an ion have if it loses 2 electrons?
A
2+
3
Q
What is the gain fo electrons called?
A
Reduction
4
Q

A
1-
5
Q
What happens to the charges in any ionic compound?
A
Balence, positive = negative
6
Q
How are the ions arranged in an ionic compound?
A
Giant Ionic Lattice
7
Q
Define ionic bonding?
A
The electrostatic attraction between oppositely charged ions
8
Q
What type of attraction is ionic bonding?
A
Very strong attraction
9
Q
Why do ionic compounds have a high melting point?
A
- Ionic bonds are very strong
- In a giant ionic lattice, there are lots of ionic bonds
- Breaking all the ionic bonds requires a large amount of energy
10
Q
What does electrical conductivity require?
A
Particles to move freely
11
Q
What is the only state ionic compounds can conduct electricity?
A
Liquid (l), or dissolved (aq) as ions can move freely
