-
Which side of the Periodic Table are the metals on?
The left hand side
-
Why are metals malleable (bendy)?
The layers of atoms can slide over each other easily
-
Why can metals conduct electricity?
They have delocalised electrons that can move through the structure
-
What is a typical property of transition metals?
They form coloured compounds
-
Where are the transition metals found on the Periodic Table?
The middle block
-
Which group of the Periodic Table are the Alkali metals in and why?
Group 1 because they have one electron in their outer shell
-
How are alkali metals different to other metals?
- They are soft
- They have low melting points
-
When an alkali metal reacts with water, e.g. Litium, what products will you get?
Lithium hydroxide + Hydrogen
-
When an alkali metal reacts with water what do you observe?
- Fizzing
- Floating on water
- Turns into a ball
- Possibly ignites/explodes
-
How does the reactivity of alkali metals change as you go down the group?
They get more reactivie
-
Which group of the Periodic Table are the Halogens in and why?
Group 7 because they have 7 electrons on their outer shell
-
At room temperature describe Chlorine, Bromine and Iodine
- Chlorine - green gas
- Bromine - orange liquid
- Iodine - grey solid
-
When a halogen, e.g. chlorine, reacts with a metal, e.g. copper, what is produced?
Metal Halide e.g. copper chloride
-
When a halogen, e.g. bromine, reacts with hydrogen, what is produced?
Hydrogen Halide, e.g Hydrogen Bromide
-
When a hydrogen halide dissolves in water what is formed?
An acidic solution
-
When a more reactive halogen takes the place of a less reactive halogen, what is the name of this type of reaction?
E.g.
Cl2 + 2KI --> I2 + 2KCl
Displacement
-
How does the reactivity of the halogens change as you go down the group?
They get less reactive
-
Which group are the Noble Gases in and why?
Group 0 because they have a full outer shell
-
Why is Helium used for balloons?
Because it has a LOWER density than air
-
What does inert mean?
Unreactive
