Covalent Bonding GCSE SPECIFICS

Question 1

What is Covalent Bonding?

Answer 1

Sharing of 2 electrons between two non metal atoms

Electrostatic force of attraction between shared pair of nuclei and negatively charged electrons

Question 2

2 Main groups of Covalent structures?

Answer 2

Simple Molecular

Giant Covalent

Question 3

Examples of Simple Moelcular?

Answer 3

Co2, H20

Question 4

Examples of Giant Covalent?

Answer 4

Graphite, Diamond, Fullerene

Question 5

Do Simple Molecular structures have a high or low melting and boiling point?

Answer 5

Low melting and Boiling point as a small amount of energy is required to overcome these weak intermolecular bonds between adjacent compounds

Question 6

Do simple Molecular Structures conduct electricity?

Answer 6

In general, Simple Molecular Structures do not conduct electricity

Question 7

What are Fullerene, Graphite and Diamond all made from?

Answer 7

Carbon atoms only

Question 8

what is the structure of Diamond?

Answer 8

Each c atom forms a covalent bond with 4 other carbon atoms. This generates a giant covalent network

Question 9

Properties of Diamond?

Answer 9

Tough
High Melting Boiling Point
These are both because the Carbon bondsare very strong
Does not conduct electricity
