1. The different parts of the periodic table

2. Key groups
Use the previous slide to transfer these to your own copy of the periodic table.
Use colours if possible. (5 mins)

3. Objectives
1. to become familiar with the main areas of the periodic table and understand the key features of these groups.
2. To be clear about the physical differences between metals and non metals

4. Outcomes
You must be able to explain the key features of your group and be able with the help of others to answer questions about each group.

5. Key terms
What is a group?
What is a period?

6. Metals vs non metals

7. Opposites attract

8. Features of metals and non-metals
Metal e.g. Silver Ag
Metalloid e.g. Antimony Sb
Non metal e.g. sulphur S
Shiny
shiny
Dull (yellow)
Ductile
brittle
Brittle
Can be hammered to shape malleable
Shatters when hammered

High density
Moderate density
Low density
High melting point
Moderate melting point
Low melting point
Some have quite low melting points some are very high
Many others are gases

9. Teams 1. Alkali metals 2. Alkali earth metals 3. Transition metals
4. rare earth metals
5. Inert gases
6. halogens
7. metalloids
8. Other non metals

10. Next lesson
In Library
Research your group and produce quick power point
Following lesson print out periodic table notes sheet from website and take notes from each persons presentation

11. Find Out See what you can find out about your group.
Features they have in common,
Chemical properties,
Physical properties,
Uses
Sources
I will add any facts I consider to be important.
Use books or internet.
You may go to the library if you need.
Make a quick power point presentation ( 3 – 5 slides)

13. Plenary 1. Why are alkali and alkali earth metals so named?
2. Iron, gold, mercury and lead are all which kind of metal?
3. Why do the inert gases not react?
4. Name a halogen and it’s use.
5. Where would you find the main gases of the air on the periodic table?
6. Name an element with features of both metals and non metals.

14. Homework
Find out about Dmitri Mendeleev and the history of the periodic table:
1. a bit of biographical detail
2. Explain how he organised the elements
3. Explain how his predictions came true.
3. For what else is he remembered in Russia?
4. How is he honoured within the periodic table?
(Include at least one piece of visual information and references).
