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?
- 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?
Cl2 + 2KI --> I2 + 2KCl
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?
