1. Science Starter:
Get notes from front.Periodic Table on RIGHT side. Notes on LEFT side. Update table of contents: Periodic Table Periodic Table Families 1.3
Send someone from group up to get ALIEN Periodic Table.

2. Science Starter: Go to my website and click on science starter article for TUESDAY! SAVE to desktop-if no laptop see me for paper copy If absent yesterday see me! Update table of contents: 14 Periodic Table Periodic Table Families 1.3 Today’s Objectives: Read closely to learn structure of Periodic Table and begin Color coding PT

3. Science Starter: Elements in a group have… a
Science Starter: Elements in a group have… a. A wide range of chemical properties b. The same atomic radius c. Similar chemical properties d. The same number of protons
Go to WED on my WEBSITE if you want to follow with PowerPoint OPEN ISN to 14 PERIODIC TABLE Today’s learning objective-
Understand the organization of PT and explain patterns of periods & groups

4. Reading the Periodic Table Lesson 1.2

5. A way of organizing & classifying elements
Dmitri Mendeleev-Russian chemist
Arranged in rows and columns based on repeating patterns of properties & atomic number
Color of chemical symbol indicates state of element at room temperature-white=gas, blue=liquid, black=solid
Background color=whether element is metal, nonmetal, metalloid

6. Columns
The vertical (up and down) columns of the periodic table (there are 18) are called groups or families.
Elements in the same group or family have similar characteristics or properties.

7. Rows The horizontal rows of the periodic table are called periods.
Elements in a period are not alike in properties.
The first element in a period is usually an active solid, and the last element in a period is always an inactive gas.

8. Rows
Atomic size (number of protons) decreases from left to right across a period.
Atomic mass (number of protons) increases from left to right across a period.

9. Rows
Metals are on the left
Non-metals are on the right

12. Elements that have not yet been named have temporary 3 letter symbols

13. Color the square for Hydrogen pink.
Lightly color all metals yellow.
Place black dots in the squares of all alkali metals.
1 ALKALI METALS
very reactive metals that do not occur freely in nature
malleable, ductile, good conductors of heat and electricity.
Low density; softer than most other metals (can be cut w/ a knife)
can explode if they are exposed to water
1 outer electron
Used in soap, fertilizers, and medicine

14. not found free in nature Metals; Silver colored
Draw a black triangle in each box in the group of alkaline earth metals.
ALKLINE EARTH METALS
not found free in nature
Metals; Silver colored
very reactive (but less reactive than alkali metals)
2 outer electrons
Used in electronics, antacids, fireworks, x-rays and metal alloys

15. TRANSITION METALS Groups 3-12
Draw black diagonal line across element box of transition metals!
TRANSITION METALS Groups 3-12
ductile and malleable, shiny, and conduct electricity and heat
iron, cobalt, and nickel, are the only elements known to produce a magnetic field.
1 or 2 outer electrons
Used in jewelry, wires, coins, metal alloys

16. RARE EARTH ELEMENTS: Lanthanides and Actinides
Shade these in RED.
many are man-made
Transitions metals-placed at bottom so not too wide
Lanthanides: shiny & reactive
Actinides: ALL RADIOACTIVE & unstable
Elements are manufactured in a lab

17. are ductile and malleable
OTHER METALS
are ductile and malleable
are solid, have a relatively high density, and are opaque
They are part of groups

18. METALLOIDS: Trace zigzag line in black than color purple B
METALLOIDS: Trace zigzag line in black than color purple B. Si, Ge, As, Sb, Te, Po, At
have properties of both metals and non-metals
some of the metalloids, such as silicon and germanium, are semi-conductors. This means that they can carry an electrical charge under special conditions. This property makes metalloids useful in computers and calculators

19. NON-METALS color these elements green
not able to conduct electricity or heat very well
very brittle, and cannot be rolled into wires or pounded into sheets
exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon).
have no metallic luster, and do not reflect light.

20. Group 13: BORON FAMILY uses: cooking, LCD displays, poisons
Group 14: CARBON FAMILY uses: graphite, diamonds, plumbing Group 15: NITROGEN FAMILY uses: refrigerant, make-up, medicines Group 16: OXYGEN FAMILY uses: medicines, water treatment, nukes, fungicide, printers, solar panels

21. HALOGENS: Color these ORANGE
"halogen" means "salt-former" and compounds containing halogens are called "salts"
7 outer level electrons
Nonmetals, very reactive
exist in all three states of matter:
Solid- Iodine, Astatine
Liquid- Bromine
Gas- Fluorine, Chlorine
USED in toothpaste, water treatment, thyroid medicines
HALOGENS:
Color these ORANGE

22. NOBLE GASES: Color these in BLUE
Inert gases; unreactive
Nonmetals
Full valence electrons so do NOT bond with others
Found in lights, balloons, electronics
