Name the 6 properties of metals
Metals are…
Lustrous (Shiny)
Usually solids at room temperature (mercury is a liquid)
Malleable (Can be hammered into different shapes)
Ductile (Can be stretched out into wires)
Good conductors of heat and electricity
Most metals rust e.g. iron
When are metal alloys formed?
When metals are mixed together
Name three alloys, what they’re made of and what they’re used for.
Bronze Copper and Tin Statues
Brass Copper and Zinc Musical Instruments
Solder Lead and Tin Soldering - Joining copper wires together
What is corrosion?
A process whereby a metal changes to it’s oxide or some other compound by combining with oxygen from the air.
What is rusting?
Iron reacts with water and oxygen to form iron oxide (rust)
what is iron oxide?
rust
What 2 things do you need for rusting?
oxygen and water
How can rusting be prevented?
by painting, greasing and galvanising (coating metal with a coat of zinc)
What is Group 1 of the Periodic Table called?
The Alkali Metals
How many electrons do the alkali metals have on their outer shell?
1
Because the alkali metals have _______ electron on their outer shell they are very __________.
one
reactive
What are the alkali metals stored in? Why?
Oil to prevent them from reacting with oxygen and moisture in the air.
Name 4 Physical Properties of the alkali metals
Shiny and easily cut with a knife
Good conductor of electricity
Low densities and float on water
Low melting points compared to other metals
What do alkali metals make when they react with air?
oxides
When Alkali metals become oxides they become_________
dull
What does lithium + oxygen make?
lithium oxide
What does sodium + oxygen make?
sodium oxide
Potassium + oxygen = ?
Potassium oxide
