Recognize how elements are arranged in the periodic table; and explain
how this arrangement illustrates the repeating patterns among elements with
similar properties, such as the relationship between atomic number and atomic
mass.

Anticipatory Set
|
Students will practice identifying elements and groups
of elements in the Periodic Table.
Ask the class who has seen the Periodic Table of
Elements, who can give the class a fact they know about the Periodic Table of
Elements, and who can identify an element on the Periodic Table of Elements.
Tell them we are going to be learning a little bit
about the history of the Periodic Table as well as how to read and interpret
it. Ask questions about why it is
important to know about the Periodic Table when studying Chemistry.

Introduction
to the Periodic Table
Slide 1: During today’s class we will learn about the
Periodic Table of Elements.
Slide
2: We will learn what the periodic
table is, how it was created, and what information can be obtained from the
table.
Slide
3: This is a modern version of the
Periodic Table of the Elements.
Slide
4: Each box contains information about
one Element and includes the Atomic Number, Atomic Symbol, Atomic Name, and
Atomic Weight.
Slide
5: The Atomic Symbol is one or two
letters that stand for the element.
The first letter is always CAPITALIZED and the second letter is always
lower case. The symbol often comes
from an ancient name of the element.
The Element (or atomic) name is the name of the element in English. It is how all scientists identify the
element.
Slide
6: The atomic number shows the number
of protons in the element. The atomic
mass number shows the number of protons plus the number of neutrons in the
element. The atomic mass is an average
of all common isotopes.
Slide
7: As we saw in the video, Mendeleev
arranged the elements by increasing atomic mass because the properties of the
elements repeated at regular intervals, or periods – thus the name: Periodic Table. The periodic table is based on the
similarity of properties and reactivity’s exhibited by certain elements. Forty years later Henri Moseley (England,
1887-1915) established that each element has a unique atomic number, which is
how the current periodic table is organized.
Slide
8: The periodic table is based on a
theory. The periodic theory, like all
theories, is constantly evolving. The
following slides give an overview of this evolution.
Slide
9: Note that the elements that are now
at the tops of the columns were at the sides in Mendeleev’s table.
Slide
10: In 1902 a new column was added for
the Noble Gases.
Slide
11: In 1914 the table was reorganized
by atomic number.
Slide
12: Since 1923 more than 26 new
elements have been added.
Slide
13: In the 1940s two new rows were
added for the lanthanoids and the actinoids.
Slide
14: Some people ask about the
placement of Helium and Hydrogen in the table.
Slide
15: The Periodic Table is a map of the
building block of matter.
Slide
16: There are two basic groups of
elements: Metals and Non-Metals. Metals have high electrical conductivity,
metallic luster, higher melting points, and are ductile and malleable. Non-metals have poor conductivity, a non-metallic
luster, and are mostly solids which are brittle.
Slide
17: There are atomic families within
each group of elements. Metals include
Alkali Metals, Alkaline Earth Metals, Transition Metals, and Semiconductors
or Metalloids. Non-Metals include
Halogens and Noble Gases.
Slide
18: Alkali Metals are On the left side
of the periodic table. They are very
reactive because they all have only one electron in their outer shell. They form +1 ions, are shiny and light in
weight, are good conductors of heat and electricity, and are very malleable
and ductile.
Slide
19: This shows the location of the Alkali
Metals.
Slide
20: Alkaline Earth Metals are the
second most reactive family of elements.
They are also located on the left side of the periodic table. They are not as reactive as the alkali
metals because they have two electrons in their outer shells. They form +2 ions, are good conductors of
heat and electricity, and are also very malleable and ductile.
Slide
21: This shows the location of the
Alkaline Earth Metals.
Slide
22: Transition Metals are found in the
center of the periodic table. They can
bond with many elements in a variety of shapes. They are good conductors of heat and
electricity, have high melting points, and are very malleable and
ductile.
Transition
metals form compounds that are brightly colored.
Slide
23: This shows the location of the
Transition Metals.
Slide
24: Semi-Conductor Metals, or
Metalloids, are intermediate conductors of heat and electricity. They can only conduct under certain conditions. They have some properties of metals and
some of non-metals.
Slide
25: This shows the location of the Semi-Conductor
Metals.
Slide
26: Non-Metals have low melting points
and boiling points. They are poor
conductors of heat and electricity, they form negative ions, and they are
very plentiful on earth.
Slide
27: This shows the location of the Non-
Metals.
Slide
28: Halogens also have low melting
points and boiling points. They are poor
conductors of heat and electricity.
They form -1 ions and are very reactive because they are only missing
one electron to have a full valence shell.
They often occur as diatomic molecules.
Slide
29: This shows the location of the Halogens.
Slide
30: The Noble Gases are located in the
far right column of the periodic table.
They occur as single atoms. Their
outer electron shells are full. They rarely
combine with other elements; they are very non-reactive. All are gases at room temperature.
Slide
31: This shows the location of the
Noble Gases.

Ask the students to tell us one thing that they learned
about the periodic table of elements as it relates to the real world. Do they see the connection?

Block 2:
Video
– Real World Elements:
Today we
are going to use what we have learned about the Periodic Table to make a
video.
Using
Animoto, or another Web 2.0 Tool, develop a video which describes a minimum of five (5) elements and
where they exist in the real world.
The assessment will be the Rubric for The Periodic Table Real World Elements.
