Covalent Bonding

Question 1

What does a covalent bond happen between

Answer 1

Between nonmetals

Question 2

What is a covalent bond

Answer 2

The electrostatic force of attraction between shared pairs of electrons and nuclei of both atoms

Question 3

What is the process of a covalent bond?

Answer 3

Sharing of electrons

Question 4

What are three possible structures of a covalent bond?

Answer 4

Simple Covalent (molecular) Fullerene. Diamond. Graphite

Question 5

What are the properties of Fullerene?

Answer 5

Soft: Material is held together by intermolecular forces, so they can slide over each other
Conducts electricity poorly ( Each carbon atom only has 3 bonds therefore there is one free/delocalised electron which cannot move between the molecules

Question 6

What are the properties of Diamond?

Answer 6

High Melting and Boiling Point (Strong covalent bonds require a large amount of heat energy to break)
Hard: Strong Covalent bonds require lots of energy to be broken

Question 7

What are the properties of Graphite?

Answer 7

Conducts Electricity: (Each carbon atom only has 3 bonds so there is a free/ delocalised electron that can move between the molecules
High Melting and Boiling Point
Lubricant: Layers of Carbon atoms can slide over each other easily
