Ionic Bonding and Compounds Flashcards
1
Q
What is ionic bonding?
A
Electrostatic connection between 2 oppositely charged ions
2
Q
How are the charged ions attracted together in ionic bonding?
A
Through an attraction caused by electrostatic forces
3
Q
How do you represent ionic bonding on paper?
A
Dot and cross diagram
4
Q
What structure do ionic compounds have?
A
Giant ionic lattice
5
Q
What is the arrangement in a giant ionic lattice?
A
- closely packed regular lattice
- strong electrostatic forces of attraction between layers
6
Q
3 properties of ionic compounds?
A
- high melting and boiling points
- conducts electricity when melted
- some can dissolve in water
7
Q
Why don’t compounds conduct electricity in solids?
A
The electrons are not free to move around so they can’t carry charge
8
Q
What is the term for free-moving electrons?
A
Delocalised electrons
