Q

Ionic bonding

A

The electrostatic attraction between oppositely charged ions.
(Held together by a giant ionic lattice)

1
Q

Ion

A

An electrically charged particle formed by the loss or gain of one or more electrons from an atom/group of atoms.

2
Q

Electrical conductivity

A

Substances conduct electricity when ions or electrons are free to move.

3
Q

Boiling and melting points

A

Are a measure of the energy required to separate the particles in a substance. Bond type is significant.

4
Q

Metallic bonding

A

The strong attraction between positive metal ions and the “sea of delocalised negatively charged electrons”.

Or

Forces of attraction between a sea of delocalised electrons and a regular array of cations.
