Title: ORGANIZING THE ELEMENTS


1
ORGANIZING THE ELEMENTS
  • Created By
  • Amy Taylor
  • Hazelwood Central High School
  • To Teacher Page To Activity

2
Teacher Page
  • Grade Level 10
  • MAP Content Standards
  • The learner will be able to understand the
    organization of the periodic table.
  • The learner will be able to show how the periodic
    table can be utilized to estimate the chemical
    properties of known and unknown elements.
  • The learner will be able to show how the periodic
    table can be utilized to estimate the physical
    properties of known and unknown elements.

3
  • MAP Content Standards Continued..
  • The learner will be able to find out the trends
    for properties of elements in the periodic table
    as they connect to the physical world.
  • Tips for Classroom Use
  • Preview the activity before using it with your
    class.
  • This activity is recommended as an introduction
    to the organization of the periodic table. You
    will want to take down or cover any periodic
    table displayed in your room to encourage
    creativity.

4
  • Tips for Classroom Use, continued...
  • This activity may take an entire class period to
    complete effectively.
  • There are element cards that you will have to
    print out and copy for your classone set is
    recommended for every 3 students.
  • Journaling
  • This activity is intended to be used in
    conjunction with journaling.
  • The notebook icon will prompt the
    students when to journal in their notebooks.

Focus on the process of problem solving with
your studentsthey need to understand not only
the facts, but the reasoning behind them. Have
them write their thoughts on paper and then
discuss them as a class.
11
An Examination of Elemental Properties
  • Recall that elements are made up of only one type
    of atom thus, all atoms of a given element have
    the same physical and chemical properties.
  • Your teacher has provided you with a set of 20
    element cards that describe some of these
    properties for 20 different elements.
  • Lets look at the element cards now...

12
Heres how each Element Card is organized...
  • Each card gives
  • the mass number
  • the measurements for melting point, boiling
    point, and atomic radius
  • the number of atoms of oxygen and chlorine that
    will combine with one atom of the element to make
    a compound.

Mass Number ___ Melting Point (C)
___ Boiling Point (C) ___ O in oxide ___
Cl in chloride ___ Atomic Radius (nm) ___
13
Cut your cards apart and then take some time to
look over the properties of the elements. With
your group, determine how you feel they are best
organized.
  • Be logical in your organization.
  • Look for similarities among the elements.
  • Look for patterns.

14
In your notebook
  • Describe how you chose to place the elements into
    groups.
  • How did you place the groups in relation to one
    another?
  • Within each group of elements, how did you decide
    to arrange the elements?

15
Compare your organization to others in your class.
  • What were the similarities?
  • What were the differences?

Discuss this with your classmates.
16
You have, in essence, created your own periodic
table. Just as there are many versions of this
table around your class, there were many
different versions that existed before our
current periodic table was adopted.
17
However, they all had a few things in common
  • They all attempted to organize the elements in a
    user-friendly fashion.
  • They all grouped elements with similar
    characteristics together.
  • They attempted to find patterns to place the
    elements in a logical way.

18
Compare and contrast your periodic table to the
one displayed in your classroom.
