Bonding and Compounds

Question 1

Why are elements and compounds classified as Ionic?

Answer 1

Ionic Substances typically have a high melting and boiling points, Ionic compounds contain ions and are held together by attractive compounds.

Question 2

Simple Molecular?

Answer 2

Simple Molecular substances only contain a few atoms

Question 3

Giant Covalent?

Answer 3

They are substances at room temperature and have very high melting and boiling points and giant covalent bonds have no charge

Question 4

Metallic?

Answer 4

One or more metal elements bonded to another element

Question 5

a)

Answer 5

those ionic compounds which have high melting and boiling points most commonly have stronger attractions between the bonds.

Question 6

b)

Answer 6

Not in a solid state
As liquids they do
and when they are in a solution where the ions are free to move

Question 7

Answer 7

diamond has four carbon atoms
graphite has three carbon atoms
diamond has no free electrons
each carbon atom of graphite has one un-bonded outer electron

Question 8

diamond and graphite structure

Answer 8

diamond has a tetrahedral arrangement
graphite has a hexagonal layered network structure
