Bonding

Question 1

3 Types of Bonds:

Answer 1

Ionic, metallic, covalent

Question 2

Ionic forms between:

Answer 2

Metals and nonmetals

Question 3

Metallic forms between:

Answer 3

Metals

Question 4

Covalent forms between:

Answer 4

Nonmetals

Question 5

Ionic structure:

Answer 5

Giant ionic lattice

Question 6

What does the ionic structure cause:

Answer 6

High melting point due to the electrostatic bonds holding it together which means a lot of energy is required to overcome them.

Question 7

Metal ions charge:

Answer 7

Positive

Question 8

Nonmetal ions charge:

Answer 8

Negative

Question 9

Can ions conduct electricity, why:

Answer 9

Yes, only when molten or dissolved in an aqueous solution. This is because then the ions are delocalised and free to move which allows them to carry a charge.

Question 10

Covalent bonds:

Answer 10

A shared pair of electrons.

Question 11

Covalent structure:

Answer 11

Simple molecular, between molecules there are intermolecular forces.

Question 12

Metallic structure:

Answer 12

Positive ions in a sea of delocalised electrons with a regular arrangement.
