10. The Periodic Table of Elements Chapter 5
Question: 
What Letter Is not Found in the Periodic Table?
Answer: The letter "J“ . Note that the letter "Q" does not appear in any official element names. However, temporary element names, such as ununquadium, do contain this letter.

12. What is the Periodic Table?
It is an organizational system for elements.
Pre-periodic table chemistry was a MESS!

13. Who created it?
In 1869, Russian chemist Dimitri Mendeleev proposed arranging elements by atomic weights and properties.
The table contained gaps but Mendeleev predicted the discovery of new elements. (He was right!)

14. Mendeleev’s Table Recorded properties of 63 elements
Physical properties
Atomic mass
Chemical properties
Density
Valence power (how it bonds)
Color
Melting point

17. The Modern Periodic Table So how is it arranged?
The genius of the periodic table is that it is organized like a big grid.
The elements are placed in specific places because of the way they look and act.
Elements are put in tows by increasing ATOMIC NUMBER
Horizontal Rows = Period
Labeled 1 to 7
Vertical columns = Groups
Labeled from 1 to 18

18. You've got Your Periods...
Even though they skip some squares in between, all of the rows go left to right.
When you look at a periodic table, each of the rows is considered to be a different period (Get it? Like PERIODic table.)

19. Periods = Rows
In the periodic table, elements have something in common if they are in the same row.
All of the elements in a period have the same number of atomic orbitals.
Every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons. It goes down the periodic table like that.

20. And you got your groups…
The periodic table has a special name for its columns, too.
When a column goes from top to bottom, it's called a group.

21. Groups = Columns
The elements in a group have the same number of electrons in their outer orbital.
Elements in a group have similar chemical and physical properties.
Every element in the first column (group one) has one electron in its outer shell. Every element on the second column (group two) has two electrons in the outer shell.
There are some exceptions to the order when you look at the transition elements, but you get the general idea.

22. Other than periods and groups, the table is divided into FAMILIES
Other than periods and groups, the table is divided into FAMILIES Families have names not numbers -May be in one column or spread across several columns

23. ALKALI METALS 1st column (NOT Hydrogen)
very reactive metals, always combine withsomething else (like salt NaCl)
malleable, ductile, good conductors of heat and electricity.
can explode if they are exposed to water
From

24. ALKLINE EARTH METALS 2nd column
Reactive metals that are always combined with nonmetals in nature
Several are important mineral nutrients (Ca and Mg)

25. TRANSITION METALS Groups 3-12 Less reactive and harder metals
Used in jewelry and construction (as “metal”)
iron, cobalt, and nickel, are the only elements known to produce a magnetic field.

26. The chemistry of fireworks: Sodium produces yellow/gold colors.
Barium creates green,
copper compounds produce blue, strontium salts give you red and titanium metals give you silver colored sparks.

27. RARE EARTH ELEMENTS
Many are man-made

28. HALOGENS (HALIDES) Elements in Group 17
Very reactive, volatile, non metals
"halogen" means "salt-former" and compounds containing halogens are called "salts"

29. NOBLE GASES Elements in Group 18
Very Unreactive - do not form compounds easily
Happy/Inert Elements (Full valance/outer shell – 8 electrons)

30. Two ways to look at the right side of the periodic table….
Other Metals, Metalloids and NonMetals
Boron, Carbon, Nitrogen, Oxygen families

31. OTHER METALS are ductile and malleable are solid, have a high density,
(1) Other Metals, Metalloids and NonMetals
OTHER METALS
are ductile and malleable
are solid, have a high density,

32. Gallium (symbol Ga and atomic number 31) has a melting point of temperature of °C (85.57 °F), which is slightly above room temperature. If you hold it in your hand long enough, it will start to melt.

33. METALLOIDS (1) Other Metals, Metalloids and NonMetals
have properties of both metals and non-metals
some of the metalloids are semi-conductors. This means that they can carry an electrical charge under special conditions. This property makes metalloids useful in computers and calculators

34. NON-METALS not able to conduct electricity or heat very well
(1) Other Metals, Metalloids and NonMetals
NON-METALS
not able to conduct electricity or heat very well
very brittle
Do not reflect light.
