1
Q
What is ionic bonding for?
A
A metal and non-metal
2
Q
How does it become stable?
A
Transfer electron from their electrostatic attraction
3
Q
What’s its shape?
A
A regular lattice shape
4
Q
Why is it hard?
A
Strong electrostatic attraction of - and + ions
5
Q
Why is it brittle?
A
Force is added -> ions shift positions -> with like charges -> repel
6
Q
Why do they have high melting and boiling point?
A
Strong electrostatic attraction - need lots of heat to break bonds
7
Q
Why are they only good conductors of electricity when in molten or water?
A
In water -> ions dissociate and move freely -> have free charge to transfer electricity
