2. THE PERIODIC TABLE
(Way of Organizing the Elements)

3. Periodic Table
Dmitri Mendeleev
Proposed the a table
for 70 Elements based
on increasing mass
and similar properties
Henry Mosely
Determined the
atomic number and
arranged the table in
order of increasing
atomic number

4. PERIODIC LAW (Periodicity)
- The Periodic Law statesthat when elementsare
arrangedin order of increasing atomic number,
there is a periodic repetition oftheir physical
and chemicalproperties.
- known as a the regular patterns of properties with
increasing atomic weight
- Both chemical & physical properties vary in a
periodic way

5. Periodic Table

8. Metals
- High electrical and heat conductivity
- High luster
- Ductile
- Malleable

9. Nonmetals
- Poor conductors of electricity and heat
- Non lustrous
- Some are gases at room temp (O2 & Cl2)
- Others are brittle solid (S)

10. Metalloids
- Exhibit properties that are intermediate between
metals & nonmetals

11. Periodic Groups and Trends

Periodic Table
ALKALI
- Group 1
- Very Reactive
- Soft Solids
- Readily combine with halogens
- Tendency to lose 1 electron

12. Periodic Groups and Trends
ALKALINE EARTH METALS
- Group 2
- Abundant metals in earth
- Not as reactive as alkali metals
TRANSITION METALS
- Group 3-12
- Important for living organisms
(as minerals)

13. Periodic Groups and Trends
INNER TRANSITION METALS
LANTHANOIDS
- Soft silvery metals
- Elements 57 to 70
ACTINOIDS
- Radio active elements
- Elements 89 to 102

14. Periodic Groups and Trends
NONMETALS
HALOGENS
- Group 17
- Salt formers
NOBLE GASES
- Group 18
- Relatively inert or nonreactive
- Gases at room temperature
