3.3 IONIC BONDING Flashcards
1
Q
what are ions arranged into?
A
giant ionic lattice
2
Q
what is ionic bonding?
A
the electrostatic force of attraction between oppositely charged ions
3
Q
is the bonding strong or weak in ionic bonding?
A
very strong attraction
4
Q
why do ionic compounds have very 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
5
Q
what does electrical conductivity require?
A
- charged particles that can move freely
6
Q
how can ionic compound conduct electricity?
A
- when they are aqueous or dissolved
- high conductivity
- can move freely
