4. Word Wall Words Set #4 Quiz Friday!
16. Colloid- a mixture in which the particles are dispersed throughout but are not heavy enough to settle out.
17. Atomic number- the number of protons in the nucleus of an atom
18. Isotopes- an atom that has the same number of protons as other atoms of the same element do but that has a different number of neutrons
19. Periodic- happening at regular intervals
20. Group- a vertical column of elements in the periodic table; elements in the same group share chemical properties

6. Periodic Table of Elements
I am Dmitri Mendeleev!
Brain Pop
I made the PERIODIC TABLE !

7. What is the PERIODIC TABLE?
The periodic table shows all known elements in the universe.
It organizes the elements by chemical properties.

8. Compare and Contrast: Elements
ELBOW PARTNERS Discussion
What are some different elements that make up humans and other organisms.
The elements alone or in combinations, make up our bodies, our world, our sun, and in fact the entire universe!

9. Periodic Table and Classes of Elements
Elements on the periodic table can be grouped into families based on their chemical properties.
Each family has a specific name to differentiae it from the other families in the periodic table.
Elements are classified as metals, nonmetals, and metalloids, by their properties.
Metals are found to the left of the zigzag line. Atoms of most metals have few electrons in their outer energy shell.

10. Periodic Table and Classes of Elements
Nonmetals are found to the right of the zigzag line. Atoms of most nonmetals have an almost complete set of electrons in their outer energy shell.
Metalloids are the elements that border the zigzag line. Atoms of metalloids have about half of a complete set of electrons in their outer energy shell. These are also called semiconductors.

11. Periods in the Periodic Table
The Periodic table is organized into rows called PERIODS.

12. Groups in the Periodic Table
It also organized into columns called GROUPS.

13. How do you read the PERIODIC TABLE?

14. What is the ATOMIC NUMBER?
The number of protons found in the nucleus of an atom Or
The number of electrons surrounding the nucleus of an atom.
Atomic numbers are arranged in numerical order.

15. What is the SYMBOL?
The symbol is an abbreviation of the element name.

16. What is the ATOMIC MASS?
The number of protons and neutrons in the nucleus of an atom.

17. A.= Atomic # P.= #Protons E.= #Electrons M.= Mass # A.= Atomic #
How do I find the number of protons, electrons, and neutrons in an element using the periodic table? Mnemonic!
A.= Atomic #
is the same as
P.= #Protons
E.= #Electrons
M.= Mass #
- minus
A.= Atomic #
= equals
N.= #Neutrons

18. Periodic Table of Elements SONG!

19. Hydrogen
The properties of hydrogen do not match the properties of any single group, so hydrogen is set apart.
1 electron in the outer level
Reactive

20. Group 1: Alkali Metals
Very reactive metals because they easily give away an electron, esp. with water
1 electron in the outer shell
Hydrogen is not a member, it is a non-metal
Conduct electricity
Sodium metal

21. Group 2: Alkaline-Earth Metals
Very reactive, but are less reactive than the alkali metals.
2 electrons in the outer shell
They are never found uncombined in nature.
Conduct electricity
White and malleable

22. Group 3-12: Transition Metals
Do not give away electrons as easily as Groups 1 and 2
Good conductors of heat and electricity
Some are used for jewelry
The transition metals are able to hold up to 32 electrons in their second to last shell.
Can bond with many elements in a variety of shapes.

23. Group 13: Boron Group
The most common element from this group is aluminum. In fact, aluminum is the most abundant metal in Earth's crust.
3 electrons in the outer level
Solids at room temperature
Most are metals

24. Group 14: Carbon Group
Carbons form proteins, fats, and carbohydrates, which are necessary for living things.
4 electrons in outer level
Solids at room temperatures
Contains metals, metalloids, and a non-metal Carbon
Silicon

25. Group 15: Nitrogen Group
Nitrogen makes up about 80% of the air you breathe!
5 electrons in the outer level
Can share electrons to form compounds
Contains metals, metalloids, and non-metals

26. Group 16: Oxygen Group
Oxygen makes up about 20% of air. It is necessary for substances to burn.
6 electrons in the outer level.
Contains metals, metalloids, and non-metals
Reactive

27. Group 17: Halogens Group
Very reactive nonmetals because their atoms need to gain only 1 electron to have a complete outer level.
7 electrons in the outer level
All are non-metals
Often bonds with elements from Group 1
Chlorine, Bromine, & Iodine

28. Group 18: Noble Gases Exist as gases Non-metals
Not reactive. VERY STABLE! They have a full set of electrons in their outer level.
8 electrons in the outer shell =FULL
All are found in small amounts in earth’s atmosphere.

29. Lanthanides and Actinides
Some are Radioactive
The rare earths are silver, silvery-white, or gray metals.
Conduct electricity

30. Science News Alert: Element 117
This is a view down the 120-meter (394-foot) long linear accelerator at the GSI Helmholtz Center for Heavy Ion Research in Germany. It created the calcium-ions used in new tests that produced element 117. For now, number 117 is the most massive element confirmed to exist!

31. Activity: Placing Elements
Use pages 286 & to color the periodic table correctly.
Color the square for hydrogen yellow. Label it “H”
Color the groups red that are very reactive metals.
Color the noble gases group orange. Label it “Noble Gases”.
Color the transition metals green. Label it “Transition Metals”.
Using black, mark the zigzag line that shows the position of the metalloids.
Color the metalloids purple.
Use blue to color all of the nonmetals that are not part of the noble gases group.
Color the metals in Groups 13–16 brown.
Circle the “actinides” in yellow and label it.
Circle the “lanthanides” in red and label it.
Circle the “alkali metals” in blue and label it.
Circle the “alkaline-earth metals” in purple and label it.
Circle the “halogens” in green and label it.
