2.2.2 Ionic (and metallic) Bonding

Question 1

what structure does ionic bonding form

Answer 1

a giant ionic lattice/ structure

Question 2

describe ionic bonding

can omit structure

Answer 2

it occurs between a metal and a non-metal via the transference of electrons from the metal to the non-metal to form ions.

structure would be giant ionic lattice

Question 3

define ionic bonding

official definition

Answer 3

A strong electrostatic attraction between oppositely charged ions.

Question 4

how is ionic bonding portrayed

Answer 4

dot and cross diagram with square brackets for the charge of the ions created

Question 5

what are the melting and boiling properties of ionic structures

Answer 5

The melting and boiling points are very high because a lot of energy is require to break the strong electrostatic attraction between the oppositely charged ions in the giant lattice

Question 6

explain conductivity in ionic structures

Answer 6

• Ionic compounds can conduct when in aqueous solutions or molten.
• This is because when in a solid state the ions are fixed in place whereas when molten or dissolved the ions are free to move throughout the structure and carry the charge

Question 7

explain solubility in ionic structures

Answer 7

ionic compounds are soluble in polar solvents.

Question 8

what structure does metallic bonding form

Answer 8

forms a giant metallic structure

Question 9

describe metallic bonding

can omit structure

Answer 9

It occurs between metals. Each lose electrons to form positive ions. This ‘lost’ electron is delocalised between the positive metal ions.
Metallic bonding is the strong electrostatic attraction between cations and delocalised electrons.

structure would be giant metallic lattice/ structure

Question 10

define metallic bonding

Answer 10

strong electrostatic attraction between delocalised electrons and fixed positive ions.

Question 11

what are the melting and boiling properties of metallic structures

Answer 11

Have a high melting and boiling points, as a lot of energy is required to break the strong electrostatic attraction between the delocalised electrons and the fixed positive ions in the giant metallic structure.

Question 12

explain conductivity in metallic bonding

Answer 12

Metals are conductive as the delocalised electrons are free to move throughout the structure and carry the charge.

Question 13

explain solubility in metallic compounds

Answer 13

metallic compounds are insoluble
