Atoms, Ions, Ionic & Covalent Bonding, Atoms & Elecron Structre, Giant Covalent Bonds (diamond & Graphite)

Question 1

What do the group numbers tell us

Answer 1

How many electrons are in the shells except in the transition metal section

Question 2

Positive =?

Negative =?

Answer 2

Metal

Non-metal

Question 3

What is the relative charge and the relative mass for Protons, Neutrons and electrons

Answer 3

Proton = +1 - 1
Neutron = 0 - 1 
Electron = -1 - vey small

Question 4

What is inside the nucleus and on the shells

Answer 4

Protons & neutrons and electrons on the shells

Question 5

What is an atomic number

Answer 5

Same number of protons

Question 6

What is a mass number

Answer 6

Protons and neutrons added together

Question 7

Explain why all atoms are neutral

Answer 7

they have the same amount of positives and negatives in the nucleus

Question 8

What are ions made up of

Answer 8

Made up from metals and non-metals

Question 9

What do ions form

Answer 9

A giant ionic lattice

Question 10

Ionic compound has high/low melting point and a low/high boiling point (choose between high and low)

Answer 10

It has a high boiling and melting point

Question 11

Does ionic compound conduct electricity when it is solid and why

Answer 11

No they do not conduct electricity because they are not free to move

Question 12

Does ionic compound conduct electricity in dissolved water and why

Answer 12

Yes they do because they are free to move and carry electrical charge

Question 13

What are the ions held together by

Answer 13

Electrostatic attraction between positive (metal) and negative (non-metal)

Question 14

Why is ionic compound hard to break

Answer 14

It has very strong bonds as it has high boiling and melting point which takes up a lot of energy

Question 15

In an ionic compound his do the outer shells get a full outer shells

Answer 15

The two elements either gains or looses electrons

When drawn :(need to put square brackets, configuration, positive or negative sign, how many electrons or losses or gains)

Question 16

How are the electrons arranged in around the nucleus

Answer 16

It is in shells 
Shell 1: 2 electrons
Shell 2: 8 electrons 
Shell 3: 8 electrons 
= 2,8,8

Question 17

What do covalent bond occur in

Answer 17

Non-metals atoms

Question 18

In covalent bond how do the elements gets a full outer shell

Answer 18

They share to gain a full outer shell

Question 19

What does two covalent bonds mean

Answer 19

Double bonds (O=O)

Question 20

Diamond: how many carbon does every other carbon have

Answer 20

4

Question 21

Diamond: do they have a very strong covalent bonds

Answer 21

Yes

Question 22

Diamonds: do they have a very high melting and boiling point and what does it show

Answer 22

Yes, it shows that the covalent bonds are strong

Question 23

Diamond: is it a giant covalent structure

Answer 23

Yes

Question 24

Diamond: is it soluble or insoluble in water.

Answer 24

Insoluble

Question 25

Diamond:des it conduct electricity

Answer 25

No

Question 26

Graphite:how many carbon bonds does it have to the other carbon atoms

Answer 26

3

Question 27

Graphite: How is graphite arranged

Answer 27

In layers which slide over each other which shoes that it feels slippery to touch

Question 28

Graphite: How many are left over when when 3 electrons are from carbon

Answer 28

1 is left over

Question 29

Graphite: what is it called when 3 electrons are combined and what does that mean

Answer 29

Sea of delocalised electrons which means that graphite can conduct electricity
