Q

Which is more reactive, Sodium or Potassium?

A

Potassium

1
Q

What is the chemical symbol for Iron?

A

Fe - This is where the word ‘ferrous’ comes from.

2
Q

What is the big block of metals in the centre of the periodic table called?

A

They are the transition metals

3
Q

Sodium is a metal, true or false?

A

True

4
Q

What are groups 1 and 2 on the periodic table called?

A

Reactive metals

5
Q

What trends occur as you go down group 1, the alkali metals?

A
  • More reactive
  • lower melting point
  • lower boiling point
6
Q

Calcium is a metal, true or false?

A

True!

7
Q

Why is it significant that all alkali metals have one outer electron?

A

It makes them very reactive and gives them all similar properties

8
Q

Transition metal’s compounds have dull colours, true or false?

A

False, they are very colourful. For example, potassium manganate(VII) is purple.

9
Q

Copper is an alkali metal or a transition metal?

A

It’s a transition metal

10
Q

Is potassium in group one or two?

A

One

11
Q

If rubidium is below potassium in group one of the periodic table, which is more reactive?

A

Rubidium

12
Q

Are transition metals good or bad conductors of heat and electricity?

A

They are good conductors of heat and electricity.

13
Q

What’s an ore?

A

A rock that contains enough metal or metal compound to make it economic to extract the metal

14
Q

How are more reactive metals extracted?

A

Electrolysis

15
Q

How are less reactive metals extracted?

A

Reaction with carbon or carbon monoxide.

16
Q

How is copper purified?

A

Electrolysis

17
Q

What makes copper useful for wiring?

A

It’s soft so easily bent and a good conductor of electricity.

18
Q

What makes copper useful for plumbing and making pipes and tanks?

A

It’s a good conductor of heat and doesn’t react with water.

19
Q

Can transition metals be bent into shape easily?

A

Yes

20
Q

What materials are transition metals useful for?

A

Construction materials.

21
Q

What’s an alloy?

A

A mixture of two or more elements, usually metals.

22
Q

Why are alloys harder than pure metals?

A

They contain atoms of different sizes, which distort the regular arrangements of atoms, making it more difficult for the layers to slide over each other.

23
Q

What do alkali metals all have in common?

A

They have to be stored in oil and handled with forceps
