Bonding, Structure And Propeties Of Matter (the Good Stuff Is On Phyisics)

Question 1

What charge do electrons have ?

Answer 1

+1

Question 2

What charge will an ion of lithium take ?

Answer 2

+1 because it need to lose the one on its outer shell

Question 3

What charge will an ion of beryllium take ?

Answer 3

+2 because it’s need to lose its 2 on outer shell as it’s easier

Question 4

What will the charge of Florine take ?

Answer 4

-1 because it’s needs to gain one as it has 7 on its outer shell

Question 5

If something gains electrons what charge will it have ?

Answer 5

Negative change

= -

Question 6

If something looses electrons what charge will it have ?

Answer 6

Positive

= -

Question 7

Why do atoms transfer electrons in ionic bonding ?

Answer 7

So that they can have full outer shells

Question 8

What is the name for a structure with oppositely charged ions joined together ?

Answer 8

Giant ionic lattice

Question 9

Define a giant ionic lattice ?

Answer 9

A network of oppositely charged ions

Question 10

Explain why some substances have a high or low melting point ?

Answer 10

Different strengths of electrostatic attractions make it easier or harder to break down

Question 11

What are the 3 states of matter ?

Answer 11

Solid

Liquid

Gas

Question 12

Whats the particle arraignment like for solid, liquid and gas ?

Answer 12

Solid- close together

Liquid- close

Gas- far apart

Question 13

Whats solid to liquid called ?

Answer 13

Melting

Question 14

Whats liquid to solid called ?

Answer 14

Freezing

Question 15

Whats Liquid to gas called ?

Answer 15

Evaporating

Question 16

what’s gas to liquid called ?

Answer 16

Condensing

Question 17

How does ionic bonding happen ?

Answer 17

Positive and negative ions form when a metal reacts with a non-metal, by transferring electrons. The oppositely charged ions are strongly attracted to each other, forming ionic bonds

Question 18

Describe the ionic lattice ?

Answer 18

In a giant ionic lattice, there are strong electrostatic forces of attraction acting in all directions between the oppositely charged ions

Question 19

What does covalent bonding form between ?

Answer 19

Two non metals

Question 20

What’s different about covalent Bonding ?

Answer 20

Thy share

Question 21

what’s the structure and bonding for diamond ?

Answer 21

There are no free elections

Strong covalent bonds

Question 22

Describe the structure and bonding for graphene ?

Answer 22

There are delocalised electrons

Carbon atoms have covalent bonds

Question 23

Whata re the properties of graphene ?

Answer 23

High melting points

Very strong

Question 24

Why are polymers hard to break down ?

Answer 24

Strong intermolecular forces e.g ethane

Question 25

What are the properties of metals ?

Answer 25

Good conductors

High mp and bp

Question 26

Whats an alloy ?

Answer 26

Mixture of two elements

Question 27

Why are alloys strong ? (Structure)

Answer 27

The atoms are arranged in layers When a force is applied, the layers may slide over each other. The greater the force needed, the harder and stronger the metal.

Question 28

What are some uses of nanoparticulate materials ?

Answer 28

medical treatments

cosmetics, deodorants and sunscreens

electronics

catalysts
