1
Q

What is metallic bonding?

( LO 1)

A

The attraction between positive ions and delocalised electrons

2
Q

Why do metals conduct electricity?

( LO 2)

A

The (outer) electrons are delocalised and free to flow between outer shells

3
Q

What are the 3 reactions of metals?

( LO 3)

A

With oxygen

With water

With acid

4
Q

What is the product of reacting metals with oxygen?

A

A metal oxide

5
Q

What are the products of reacting metals with water?

( LO 3b )

A

A metal hydroxide plus hydrogen

6
Q

What are the products of reacting metals with acids?

( LO 3c )

A

A salt plus hydrogen

7
Q

How many electrons do metal lose?

A

The number of outer electrons they have

8
Q

What charge is on metal ions?

A

The positive charge equivalent to the number of electrons they have lost.

9
Q

How does the reactivity of metals affect their reactions with water, acids, and oxygen?

( LO 4 )

A
10
Q

How are soluble salts made using metals?

( LO 5 )

A
11
Q

What is meant by oxidation?

( LO 6b )

A

The loss of electrons

12
Q

Why do metals lose electrons when they react?

A

To obtain a full valence shell

13
Q

What do we call naturally occurring metal compounds?

A

Ores

14
Q

What are the 3 ways of extracting metals from ores?

A

Electrolysis ( Al and above)

Heating with carbon ( Cu to Mg)

Heating ( Below Cu)

15
Q

What type of bonding is found in almost all metallic compounds?

A

Ionic bonding

16
Q

What do we call the process of making metal ions into metal atoms during extraction?

A

Reduction (gain of electrons)

17
Q

What are the 3 methods of extracting metals and which metals can be extracted by each method?

A
