Answer 2

Right.

Question 3

Rows are called…

Answer 3

Columbs

Question 4

Vertical columns are called…

Answer 4

Groups

Question 5

What does the group number tell you about the element

Answer 5

How many electrons the have in their outer shell

Question 6

What type of ion do metals form when they react

Answer 6

Positivte ion

Question 7

What do atoms generaLly react to form

Answer 7

A full outershell

Question 8

What type of bond do metals have

Answer 8

Mettalic bond

Question 9

What does a metallic bond cause metals to have

Answer 9

A similar basic physical propeties

Question 10

What are metals great at

Answer 10

Conducting heat and electricity

Question 11

What are group 1 elements know as

Answer 11

Alkali metals

Question 12

What elements are in group 1

Answer 12

Lithium, sodium, pottasium, rubidium, caesium and francium

Question 13

How many electrons do group 1 elements contain in their outershell and what does this mean

Answer 13

They all have 1 electron in their outershell meaning this makes them very reactive and have similar properties.

Question 14

What are some properties of group 1 elements

Answer 14

Soft, low density

Question 15

Trends in group 1

Answer 15

• as you go down, increase in reactivity - as you go down, the electron gets further away from nucleus meaning the attraction between nucleas decreases
• meaning lower melting points and boiling points as you go down
• higher relative atomic mass as you go down

Question 16

What ion do alkali metals form

Answer 16

+1 ion

Question 17

What happens when alkali metals react with water?

Answer 17

They react vigorously. More reactive as you go down. Lithium pottasium sodium float and move around whilst fizzing vigourously. They also produce hydrogen

Question 18

What is produced when reacted with chlorine

Answer 18

White salts called metal chlorides.

Question 19

What happens when alkali metals react with oxygen

Answer 19

They form metal oxide.
Lithium = lithium oxide
Sodium = sodium peroxide & sodium oxide
Pottassoum = pottassium peroxide & pottassium superoxide

Question 20

What are group 7 elements known as

Answer 20

Halogens

Question 21

Halogens and their appearence

Answer 21

Fluorine - very reactve, poisonous yellow gad
Chlorine - fairly reactive, poisenous dense green gas
Bromine - dense, poisonous red-brown volatile liquid
Iodine - dark grey crystalline solid or a purple vapour

Question 22

Trends of halogens

Answer 22

As you go down…
Less reactive - harder to gain an extra electron as further away from nucleus
Higher melting and boiling points
Higher relative atomic masses

Question 23

How many electrons are in halogens outer shell

Answer 23

7

Question 24

What can halogens form to get a full outershell?

Answer 24

Molecular compounds: share electrons via covalent bonding with other non metals. The compounds which form all have a simple-molecular structure

Question 25

What ion do halogens form

Answer 25

1- ion called halides when they react with metals. These all have ionc structures

Question 26

In halogens, how can a displacement reaction occur?

Answer 26

When a more reactive halogen reacts with a salt of the less reactive one

Question 27

What are group 0 elements called

Answer 27

Noble gases

Question 28

How many electrons do noble gases have in their outer shell and what does this mean

Answer 28

8 meaning they are extremely unreactive as they have a full outershell

Question 29

What are noble gases all?

Answer 29

Inert colourless gases.

Question 30

What do noble gases exist as

Answer 30

Monatomic gases

Question 31

What are the patterns in properties in noble gases!

Answer 31

Boiling points Increase as you go down.

Question 32

How do you find out the trend in reactivity in a group in the period table?

Answer 32

If the elements are trying to lose 1 or more electrons, the reactivity will increase because as the electrons get further away from the nucleus, it is easier to lose the electron. But if the elements are trying to gain, the reactivity decreases as it is harder to gain electrons as the electrons are further away from the nucleus

Question 33

What does electrostatic attraction depend on?

Answer 33

-the distance between the outermost electrons and the nucleus -the number of occupied inner shells of electrons which have a shielding effect -the size of the positive charge on the nucleus

Question 34

What to factor to decide how easy it is for atoms to lose or gain electrons from their outershell?

Answer 34

-the increased nuclear charge -due to extra protons in the nucleus

Question 35

Problems with categorising elements in the 1800s:

Answer 35

-scientists had no idea of atomic structure or of protons -only thing you could measure was atomic weight

Question 36

Why did mendaleev leave gaps?

Answer 36

To make sure thst elements with similar properties stayed in the same group. Some of these groups indicated the existence of undiscovered elements

Question 37

What did the discovery of isotopes confirm?

Answer 37

That mendaleev was correct not to place elements in a strict order of atomic weight but to also account for their properties

Question 38

Physical properties of metal?

Answer 38

-strong and can be bent or hammered -great at conducting heat and electricity -high melting and boiling points

Question 39

Non-metal physical properties?

Answer 39

-dull looking -brittle -low density -dont conduct electricity
