1. Warm Up
Need notebook, colored pencils, glue and textbook(if you have it)
List everything you currently know about the periodic table of elements.
Tell me what you would like to know about the periodic table.

2. Welcome
You will need your notebook, pencils, tape or glue stick and colored pencils.
Take out vocab squares and foldable
Get sheets off the front table with lamp
Complete before you read on Anticipated guide on half sheet.

3. The Periodic Table

4. The Periodic Table
Dmitri Mendeleev ( )

5. Dmitri Mendeleev 1) Father of the period table.
2)First to systematically arrange elements
3)Elements were arranged
by their atomic masses
Elements were grouped
together according to
their similarities
*Empty spaces were left
where he predicted
undiscovered elements
should go

6. Mendeleev’s Published Periodic Table of Elements
Why do you think there are question marks here?

7. Henry Moseley
He concluded that the number of protons in an atom is its atomic number
In 1914, his work led to a revision of the periodic table

8. How is the Modern Periodic Table Arranged?
Elements are now arranged by their atomic numbers
Elements are arranged in periods and groups

9. What are Periods in the Periodic Table
A horizontal row is called a period

10. A vertical column is called a group
What are Groups?
A vertical column is called a group
Elements in the same group have similar properties and reacts in similar ways!

11. How is the Periodic Table Read?
Each square gives particular information about the atoms of an element
Atomic
number
Atomic
Mass 13
Symbol
Atomic number is the
number of protons in
the nucleus
Average atomic mass
(amu)the number of all
isotopes of an element Al
26.981

12. What are the division of the Periodic Table?

13. Metal: Elements that are usually solids at room
temperature. Most elements are metals.
Non-Metal: Elements in the upper right corner
of the periodic table. Their chemical
and physical properties are different
from metals.
Metalloid: Elements that lie on a diagonal line
between the Metals and non-metals.
Their chemical and physical
properties are intermediate between the metals and nonmetals.

14. What metal is not a solid
What are Metals?
Location
Found on the left of the zigzag line/staircase on the periodic table (exception  Hydrogen)
Chemical Properties
Have few electrons in their outer energy level, thus lose electrons easily
Physical Properties
Ductile (easily drawn into a wire), good conductors of heat and electricity, malleable (easily shape), shiny, most are room temperature 79 Au 11 Na
22.990

What metal is not a solid
@ room temperature?

15. What are Reactive Metals?
Metals that are more likely to undergo a chemical change or reaction
Always combined with something else in nature
Alkali metals (group 1) are the most reactive metals. Combine to form salts
Alkaline Earth metals (group 2) second most reactive metal group. Some are important nutrients like Calcium and magnesium.

16. What are Transitional Metals?
Groups in the middle
Groups 3-12
Generally less reactive then other metals
Good conductors of heat and electricity.
Some are used for jewelry, currency and construction

17. What are Non-Metals?
Location
Most found to the right of the zigzag line/staircase on the periodic table
Chemical Properties
Most have almost full outer energy levels, thus they tend to gain electrons; some have completely full outer level
Physical Properties
not ductile or malleable, not shiny, poor conductors of heat and electricity, most are solid, but some are gas at room temperature 17 Cl

18. Hydrogen Hydrogen belongs to a family of its own.
Hydrogen is a diatomic, reactive gas.
Hydrogen was involved in the explosion of the Hindenberg.
Hydrogen is promising as an alternative fuel source for automobiles

19. Very reactive and are often bonded with elements from Group 1
What are Halogens?
Group 17
All are non-metals
Very reactive and are often bonded with elements from Group 1
form salt compound
7 electrons in the outer shell
Used as disinfectants and to strengthen teeth

20. What are Noble / Inert Gases?
Group18
Non-metals - Exist as gases
Not reactive with other elements
8 electrons in the outer shell = Full /stable
Helium (He) has only 2 electrons in the outer shell = Full/ stable

21. What are Metalloids?
Location
Border the zigzag line/staircase on the periodic table
silicon is the most common
Found in semi conductors
Examples: computers, cell phone
Physical Properties
have properties of both metals and non-metals 14 Si

22. Rare Earth Metals Some are Radioactive
The rare earths are silver, silvery-white, or gray metals.
Conduct electricity
Group 1
Group 18
Group 2
Group 17

23. Four chemical families of the periodic table: the alkali metals (IA), the alkaline earth metals (IIA), halogens (VII), and the noble gases (VIIIA).
Group 1
Group 18
Group 2
Group 17

24. Periodic Table Rap

25. Directions
On your periodic table indicate where your periods and groups are located. You can draw arrows to indicate the direction.
Number your periods on left of the periodic table.
Trace the zig-zag line in Black
Identify the following on your table and color them as indicate. Metals = Metalloids= Nonmetals=
Do not color too dark, you need to see the element info.
At the top of your table make a coding key to include the
name and color of each element type.
Name group 1 and outline it in red
Name group 2 and outline it in orange
Name group 3-12 and outline it in blue
Name group 17 and outline in purple
Name group 18 and outline in green
Label lanthanide and actinides elements See page D in book
