Ionic Structure, Bonding and Properties Flashcards
1
Q
what is the structure of an ionic compound?
A
the ions are arranged in a giant ionic lattice
2
Q
what is the definition of ionic bonding?
A
ionic bonding is the electrostatic attraction between oppositely charged ions
3
Q
what is a feature of ionic bonding?
A
- it is always a very strong attraction
4
Q
what is a feature of ionic bonding?
A
- it is always a very strong attraction
5
Q
why do ionic compounds have high melting points?
A
- the 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
6
Q
why do some ionic compounds have higher melting points?
A
- their ions have higher charges
- this makes the attraction between the ions even stronger and harder to break
7
Q
what does electrical conductivity require in ions?
A
charged particles that can move freely
