Chemical Bonding (DIRT)

Question 1

What is Covalent Bonding

Answer 1

A shared pair of Electrons ( Between two non metals)

Question 2

What Is Ionic Bonding

Answer 2

Electrons are shared (Between a metal and a non metal)

Question 3

What are the Forces of Ionic and Covalent bonding

Answer 3

Ionic- Electrostatic force of attraction between oppositely charged Ions
Covalent-Strong Covalent bonds between atoms, Weak Intermolecular forces between molecules

Question 4

Why does liquid Iodine not conduct Electricity?

Answer 4

No Delocalised Electrons so cannot carry charge through the structure

Question 5

Explain why Graphite is so soft and slippery

Answer 5

Because the layers are held together by weak intermolecular forces and layers can slide over each other because of the weak intermolecular forces

Question 6

What are the melting point and boiling point and conductivity of a Giant Covalent?

Answer 6

Melting Point- the melting point of a Giant Covalent is very high because of the many strong covalent bonds
Boiling Point- the boiling point of a Giant Covalent is very high because of the strong Intermolecular forces that requires a lot of energy to break
Conductivity- the Giant Covalent does not conduct because there are no free electrons/charges except there are free electrons/charges in Graphite

Question 7

Describe and Explain the melting point and boiling and conductivity of Simple Covalent

Answer 7

Melting point- The melting point of Simple Covalent is low because it does not require much energy to break the weak Intermolecular forces
Boiling point- The Boiling point of Simple Covalent is low because it does not require much energy to break the weak Intermolecular forces
Conductivity- Simple Covalent does not conduct because there are no charged Electrons

Question 8

Describe and Explain the melting point and boiling and conductivity of Giant Metallic

Answer 8

Melting point-The melting point of Giant Metallic is high because of the strong Electrostatic force of attraction that requires a lot of energy to break
Boiling point-The boiling point of Giant Metallic is high because of the strong Electrostatic force of
Conductivity- Giant Metallic does conduct because the Electrons can move throughout the structure

Question 9

Describe and Explain the melting and boiling points and conductivity of Giant Ionic

Answer 9

Melting point-The melting point of Giant Ionic is high because of the strong electrostatic force that requires a lot of energy to break
Boiling point-The boiling point of Giant Ionic is high because of the strong electrostatic force that requires a lot of energy to break
Conductivity- Giant Ionic conducts because the electrons/charges can move
