2. I AM DMITRI
MENDELEEV!
I MADE THE PERIODIC TABLE !

3. PERIODIC TABLE OF ELEMENTS
- A toll that aids in identifying the physical
and chemical properties of elements.
- Helps you to remember the chemical
symbols of elements; their atomic size, and
their metallic properties and nonmetallic
properties.

4. PERIODIC TABLE OF ELEMENTS
- Horizontal rows -> period or series
- Vertical column -> group or family

5. PERIODIC TABLE OF ELEMENTS
- Group IA – Alkali Metals
- Group IIA – Alkaline Earth Metals
- Group IIIA – Boron Family
- Group IVA – Carbon Family
- Group VA - Nitrogen Family
- Group VIA – Oxygen Family
- Group VIIA – Halogens Family
- Group VIIIA – Noble Gases

6. PERIODIC TABLE OF ELEMENTS

7. PERIODIC TABLE OF ELEMENTS
- Sanderson line – ladder-like line that
divides metals and nonmetals.
- Elements to the left are metals while on the
right are nonmetals.
- B, Si, Ge, As, Sb, Te, Po and At are called
metalloids.

9. Properties of Metals
• Good conductors of heat and electricity
• Lustrous and shiny.
• Ductile (can be stretched into thin wires)
• Malleable (can be pounded into thin
sheets)
• High melting point
• Usually solid (except Hg) at room
temperature
• A chemical property of metal is its
reaction with water which results in
corrosion.

10. Properties of Non-Metals
• Poor conductors of heat and
electricity
• Non-lustrous (dull appearance)
• Not ductile or malleable
• Brittle and break easily
• Many non-metals are gases.
• Maybe solid, liquids or gases at
room temperature
Sulfur

11. Properties of Metalloids
• Have properties of both metals
and non-metals
• Solids that can be shiny or dull.
• Conduct heat and electricity
better than non-metals but not as
well as metals.
• They are ductile and malleable.
Silicon

12. Region: Metals

13. Group1: Alkalai Metals
• 1 valence
electron
• Very
Reactive

14. Group 2: Alkaline Earth Metals
• 2 valence
electrons
• Very
reactive,
but less
than alkali
metals

15. Groups 3 – 12: Transition Metals
• 1-2 valence
electrons
• Less reactive
than alkaline
earth metals
because they
don’t give away
their electrons
as easily
• Bottom 2 row
are the
Lanthanide &
Actinide series

16. • Lanthanide Series:
– shiny reactive metals
– Most found in nature
• Actinides Series:
– radioactive and
unstable
– Most are man-made &
not stable in nature

17. Region: Metalloids

18. Region: Nonmetals

19. Group 17: Halogens
• 7 valence
electrons
• Very
reactive
• Nonmetals

20. Group 18: Noble Gases
 8 valence
electrons (except
He which only
has 2)
 “Happy” because
their outer
electron shell is
filled!
 NON
REACTIVE
(inert)
gases
 Nonmetals

21. WRITE THE NAME OF THE
FOLLOWING ELEMENTS

10. Ag

22. 11-15. Write 5 properties of metals
16-20. Write 5 properties of nonmetals
21-25. Write 5 properties of metalloids
26-40. Write 15 metallic elements.
41-52. Write 12 nonmetal elements
