Iobnic Bonding

Question 1

What is the structure of an ionic compound like?

Answer 1

Arranged in a giant ionic lattice

Question 2

What is ionic bonding

Answer 2

The electrostatic attraction between oppositely charged ions

Question 3

How strong are ionic bonds

Answer 3

Ionic bonding is always a very strong attraction

Question 4

Ionic properties:

Answer 4

.high melting points
.electrical conductivity

Question 5

Why do ionic compounds have high melting points

Answer 5

.ionic bonds are very strong
.in a giant ionic lattice there are lots of ionic bonds
.breaking all the ionic bonds requires a large amount of energy

Question 6

Why do ionic compounds conduct electricity

Answer 6

.electrical conductivity requires charged particles that can move freely
.when solid - ionic compounds dont conduct electricity because ions cannot move freely
.when liquid - ions can move freely so conduct

Question 7

When do ionic compounds conduct electricity

Answer 7

When liquid

Question 8

How do metal ions form

Answer 8

.metal ions tend to lose all their outer shell electrons to gain a full outer shell and be more stable
.they become positively charged
.loss of electrons is called oxidation

Question 9

How do non metal ions form

Answer 9

.non metal atoms tend to gain electrons to fill their outer shell to fill their outer shell and become more stable
.they become negatively charged ions
.the gain of electrons is called reduction

Question 10

What is the loss of electrons called

Answer 10

Oxidation

Question 11

What is the gain of electrons called

Answer 11

Reduction
