Tennessee SPI Objective:
Use the periodic table to determine the properties
of an element.
Instructions
1) First click on "View" from the top-menu bar.
2) Then click on "Slide Show" from the drop-down menu.
3) Then use the right-arrow button on your keyboard to advance through this presentation.
Check for Understanding
Identify the atomic number, atomic mass, number of protons, neutrons, and electrons in atoms using the periodic table.
Essential Question
How do I use the periodic table to determine the
atomic number, the atomic mass, the number of
sub-atomic particles, & other properties in an atom?

2. Metals (on the left and middle)
Periodic Table in 3 Sections
(1) Metals, (2) Metalloids, & (3) Nonmetals
Metals: (on the left & middle)
Metalloids: (on the zig-zag line)
Nonmetals: (on the right)
Nonmetals
(on the right)

(on the left and middle)
More Metals
These are actually located above
in the 6th & 7th periods (rows) in group (column) three)

3. Periodic Table in 3 Sections
(1) Metals, (2) Metalloids, & (3) Nonmetals
Metals: (on the left of the periodic table)
metal elements tend to be shiny, malleable, ductile, and are good conductors of electricity and thermal energy (heat)

4. Periodic Table in 3 Sections
(1) Metals, (2) Metalloids, & (3) Nonmetals
Nonmetals: (on the right side of the periodic table)
Nonmetal elements are generally not shiny, not malleable, not ductile, and are not good conductors of electricity or thermal energy (heat)

5. Periodic Table in 3 Sections
(1) Metals, (2) Metalloids, & (3) Nonmetals
Metalloids: (on the zig-zag line)
Have some properties of metals and some properties of nonmetals, are called semi-conductors

6. Notes Science Periods: SPI 0807.9.9 Periodic Table
The rows are called periods, and there are seven of them
Per 1
Per 2
Per 3
Per 4
Per 5
Per 6
Per 7
From period 6
From period 7

7. The period number tells you the number of electron shells
All elements in the same period have the same number of electron shells
1st Period = 1 Shell
2nd Period = 2 Shells
3rd Period = 3 Shells
4th Period = 4 Shells
Lithium Atom
This atom has two electron shells.
So it is located in the second period.

8. The period numbers reveal the number of electron shells
Example: Every element in period 2 has 2 electron shells
Example: Every element in period 3 has 3 electron shells
Per 1
Per 2
Period 2 (Each element here has 2 electron shells)
Per 3
Period 3 (Each element here has 3 electron shells)
Per 4
Per 5
Per 6
Per 7

Stand and Stretch!
You have been sitting for a mighty long time.
Let's take a 1 minute break to stand and stretch.

Periodic Table
Notes
Science
Groups: The columns are called groups (also called families)
There are 18 groups 1 18 2 13 14 15 16 17 3 4 5 6 7 8 9 10 11 12

11. Notes Science SPI 0807.9.9 Periodic Table
The group number (in some cases) can reveal how many electrons are in the outer most shells.
These are called the valence electrons
Example: Lithium (see below-left) has one valence electron, so it is in group (column) one.
Example: Beryllium (see below-right) has two valence electrons, so it is in group (column) two.
Lithium Atom
Beryllium Atom
x 4
x 5
2 Valence Electrons
1 Valence Electron

12. (called transition metals) V for vertical = V for valence electrons
SPI
Periodic Table
Notes
Science
Again, the group number can reveal the number of valence electrons
Note: However this only works for groups 1 to 2 and 13 to 18
(see below) 1 18 2 13 14 15 16 17
This "trick" does not work with groups 3 to 12
(called transition metals)
Memory Trick:
Remember V =V
V for vertical = V for valence electrons

13. Notes Science SPI 0807.9.9 Periodic Table
Again, the group number can reveal the number of valence electrons
Reminder: This "trick" only works for groups 1 to 2 and 13 to 18
(see below) 1
Example: Every element in group one has only one valence electron. 2
Example: Every element in group two has exactly two valence electrons.

14. Simply subtract ten from each number
SPI
Periodic Table
Notes
Science
Again, the group number can reveal the number of valence electrons
Reminder: This "trick" only works for groups 1 to 2 and 13 to 18
(see below)
For Groups 13 to 18:
Simply subtract ten from each number 18
Example: For group 13 subtract ten, and you get three. So every element in group 13 has three valence electrons 13 14 15 16 17
Example: For group 14 subtract ten, and you get four. So every element in group 14 has four valence electrons

15. Reactivity in Elements (called transition metals)
For groups 1 to 2:
Reactivity increases from right to left
For groups 13 to 17:
Reactivity increases from left to right
(Leave out group 18…they are non-reactive!)
Groups 1 to 2
Groups 13 to 17 1 2 13 14 15 16 17
Non-reactive
Again, ignore groups
3 to 12 for now
(called transition metals)
