1. Elements and the Periodic Table

2. Period
Period – Row of elements in periodic table

3. Group
Group – column of elements in periodic table

4. Alkali metals Alkali metals – group one elements (not H)
Soft, highly reactive

5. Alkaline earth metals Alkaline earth metals – group two elements
Light, reactive

6. Halogens Halogens – group 17 elements
Most reactive group of periodic table

7. Noble Gases Noble Gases – group 18 elements
Very stable, rarely react with other chemicals

8. Elements and the periodic table1)
green  metalloids
Pink  non-metals
Blue metals
2) what is the exception to metals and non-metals
3) give two reason why this is where it is?

9. Elements and the periodic table
4) list four properties of metals
5) List four properties of non-metals

10. Elements and the periodic table
6) Explain the term chemical family (group)

11. Elements and the periodic table

12. Elements and the Periodic Table
8B) give a definition of each part- charge and location
Proton , inside nucleus
Neutron neutral, inside nucleus
Electron , inside nucleus

13. Elements and the Periodic Table
9) What is an ion?
A charged atom
10) how is an ion formed?
Loses or gains electrons

14. Bohr Rutherford Diagrams

15. Bohr Rutherford Diagrams
Graphically illustrate the chemical structure of elements of the Periodic Table
Electrons are around nucleus in orbits
Each orbit can only contain a certain number of electrons (2 electrons in first orbit then 8 in each after)
# protons = atomic #
#neutrons = mass# - atomic#
#electrons = atomic #
