Ionic and Covalent lattices, and Covalent Molecuels

Question 0

What are some properties of ionic lattices

Answer 0

High melting point, hard to separate, only able to conduct electricity when melting or dissolved

Question 1

What is an ionic lattice

Answer 1

A structure like a lattice between a metal and a non metal

Question 2

What happens when ionic lattices conduct electricity

Answer 2

They decompose back into their original elements, metal on the cathode, the non metal on the anode

Question 3

Give one example of giant covalent lattices.

Answer 3

Diamond, graphite or silicon dioxide (sand)

Question 4

Covalent lattice properties?

Answer 4

High melting and boiling points

Question 5

What are graphites properties

Answer 5

Has layers on its structure, these layers move freely and the bonds are weaker so they break off, this is why we are able to write with it.
Soft and brittle
The layers move freely so you are able to use it as an electrical conductor

Question 6

Covalent molecules properties, give two examples

Answer 6

No charged particles that are free to move
Unable to conduct electricity
Insoluble
Strong bonds with atoms in molecule, weak attractions between the molecules intermolecular forces
Low melting and boiling points
