Periodic Table

1) What is the Periodic Table ?
Every element has a name and a symbol (one or two letters)
Depending on the temperature every element can be changed into solid, liquid or gas.
The periodic table provides a list of all the different elements
The table is divided into groups (which go down) and periods (which go across)
For example the first group are all soft, shiny metals
All the elements in a column/group have similar properties
The properties of the elements change as you go down the column.
Elements at the bottom of the column/group act more violently than those at the top.

2) How many elements are there in the periodic table ?
118 in total. 95 metals (including 7 metalloids), 22 non-metals

3) Can you describe some physical properties of Metals ?
Metals conduct electricity
Metals conduct energy
Metals are strong and tough
Metals are shiny when polished
Metals are sonorous
Metals are ductile
Metals have high densities
Metals have high melting and boiling points

4) Can you describe some physical properties of Non-Metals ?
Non-metals don't conduct electricity
Non-metals don't conduct energy (by heating well)
Non-metals are not strong or hard wearing
Non-metals are dull
Non-metals are brittle
Non-metals have low densities
Non-metals have low melting and boiling points

5) What is a Metalloid ?
An element intermediate in properties between the typical metals and non-metals.

6) Can you list the 7 metalliods ?
