Ionic bonding - 3.3 Flashcards
1
Q
what is the loss of electrons called?
A
oxidisation
2
Q
what is the gain of electrons called?
A
reduction
3
Q
what is ionic bonding?
A
ionic bonding is the electrostatic attraction between oppositely charged ions
4
Q
how is an ionic compound arranged?
A
giant ionic lattice
5
Q
Why do ionic compounds have high melting points?
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
6
Q
When can ionic compounds conduct electricity and not conduct electricity?
A
solid
- no conductivity
- ions can’t move freely
liquid or dissolved
- high conductivity
- ions can move freely
