Metals And Non-Metals

Question 1

Metals

Answer 1

Form positive ions when they react

Strong
Malleable
Good conductors of heat and electricity
Have high boiling and melting points

Question 2

Non-metals

Answer 2

Dull-looking
Brittle
Don’t conduct electricity
Have a lower density

Question 3

Transition metals

Answer 3

Typical metals 
Good conductors of heat and electricity 
Very dense
Strong
Shiny 

Can have more than 1 ion
Often coloured
Often make good catalysts

Question 4

Group 1 elements

Answer 4

Alkali metals

Soft
Low density 
Have 1 electron in outer shell 
Very reactive 
Going down the group:
Increasing reactivity 
Lower melting and boiling points 
Higher relative atomic mass

Form ionic compounds with non-metals

Question 5

Alkali metals when reacting with:

Water

Chlorine

Oxygen

Answer 5

Water: react vigorously - produce hydrogen gas and metal hydroxides
More reactive - more violent reaction
Amount of energy released increases down the group

Chlorine: react vigorously- form metal chloride salts
Reactivity increases as you go down group so reaction gets more vigorous

Oxygen: form metal oxide

Question 6

Group 7 elements

Answer 6

Halogens

Non-metals with coloured vapours

As you go down group:
Less reactive - harder to gain an extra electron
Higher melting and boiling points
Higher relative atomic masses

Question 7

What do halogens form when reacting with metals?

Answer 7

Ionic bonds

Question 8

What do more reactive halogens do?

Answer 8

Displace less reactive ones

Question 9

Group 0 elements

Answer 9

Noble gases

Full outer electron shell
So don’t react a lot

Monotomic gases - single atoms not bonded to each other

All colourless gases at room temperature
Non-flammable

Question 10

What happens as you go down group of noble gases?

Answer 10

Boiling points increase - greater intermolecular forces between each atom
