The same number of occupied shells
The same atomic number
The same number of neutrons
2.
Which elements are found in Group 1?
The alkali metals
The halogens
The noble gases
The transition metals only
3.
How does Group 1 reactivity change down the group?
It increases
It decreases
It remains exactly constant
It disappears after lithium
4.
Which observation is expected when potassium reacts with water compared with lithium?
Potassium reacts more vigorously
Potassium does not react
Lithium always explodes more strongly
Both reactions are identical in every way
5.
What products form when a Group 1 metal reacts with water?
A metal hydroxide and hydrogen
A metal chloride and oxygen
A metal oxide only
Carbon dioxide and water
6.
Why are Group 1 metals stored under oil?
To prevent reaction with oxygen and water vapour
To make them denser
To turn them into non-metals
To cool them below absolute zero
7.
Which Group 1 metal is most reactive among lithium, sodium and potassium?
Potassium
Lithium
Sodium
They are equally reactive
8.
How does the melting point of Group 1 metals generally change down the group?
It decreases
It increases without exception
It remains identical
It becomes the boiling point
9.
Which elements are found in Group 7?
The halogens
The alkali metals
The noble gases
All metals
10.
How does Group 7 reactivity change down the group?
It decreases
It increases
It remains constant
It alternates randomly
11.
Which halogen is most reactive among chlorine, bromine and iodine?
Chlorine
Bromine
Iodine
They have equal reactivity
12.
What happens when chlorine is added to potassium bromide solution?
Chlorine displaces bromine
Bromine displaces chlorine
No particles are present
Potassium becomes a noble gas
13.
Why can chlorine displace bromide ions from a compound?
Chlorine is more reactive than bromine
Bromine is more reactive than chlorine
Chlorine is a metal
Bromide ions contain no electrons
14.
How does the physical state of the halogens change down Group 7 at room temperature?
From gases to liquid to solids
From solids to plasma only
All remain gases
All remain liquids
15.
Which statement about halogen colour down the group is generally correct?
The colour becomes darker
Every halogen is colourless
The colour becomes pure white
Colour has no observable trend
16.
Which elements are found in Group 0 or 18?
The noble gases
The alkali metals
The halogens
The metalloids only
17.
Why are noble gases very unreactive?
They have full outer electron shells
They contain no electrons
They have empty nuclei
They are all solids
18.
Why is argon used inside some lamps?
It is unreactive and does not react with the hot filament
It burns the filament faster
It is a very reactive metal
It removes every electron from the glass
19.
How does the boiling point of noble gases generally change down the group?
It increases
It decreases to zero
It stays exactly the same
It becomes unrelated to particle size
20.
An unknown element has one outer-shell electron and reacts strongly with water. Which group is it likely to be in?
Group 1
Group 7
Group 0
No group
21.
An element has seven outer-shell electrons and forms a salt with sodium. Which group is most likely?
Group 7
Group 1
Group 0
Group 2 only
22.
Which pair is arranged from more reactive to less reactive?

Iodine, bromine, chlorine
Bromine, iodine, chlorine
Iodine, chlorine, bromine
23.
Which pair is arranged from less reactive to more reactive for Group 1?
Lithium, sodium, potassium
Potassium, sodium, lithium
Sodium, potassium, lithium
Potassium, lithium, sodium
24.
Why can trends be used to predict properties of an element lower in a group?
Elements in a group have related outer-electron structures and show systematic changes
All elements in a group are identical
Atomic number decreases down every group
Predictions do not use evidence
25.
A new noble gas is discovered below radon. Which property is most reasonable to predict?
It will be very unreactive and have a higher boiling point than lighter noble gases
It will react violently with water like potassium
It will have one outer electron
It will be a strongly coloured halogen
