Ionic, Covalent, & Metallic Bonding

Question 0

Ionic bonding

Answer 0

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

Question 1

Ion

Answer 1

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

Question 2

Electrical conductivity

Answer 2

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

Question 3

Boiling and melting points

Answer 3

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

Question 4

Metallic bonding

Answer 4

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.
