16. What is the periodic table?
It is a chart that organizes the elements by their increasing atomic numbers as well as by their physical and chemical properties.

17. Who made the periodic table and when was it created?
A Russian chemist and inventor named Dmitri Mendeleev created the periodic table in 1869.

18. 3) What ability did the periodic table have?
The periodic table was designed to make room for and predict the existence of elements that had not yet been discovered.

19. Elements
Atomic Number: # of protons in nucleus (which = electrons) top number
Symbol: 1 to 2 letters, first letter is capital (based off Latin name)
Atomic mass: mass of the atom -in amu (bottom #)

20. Elements are made of atoms:
Atoms are made of protons, neutrons in the middle, surrounded by electrons

21. Amu= atomic mass unit: both protons and neutrons have a mass of 1 amu
atomic mass is equal to # of protons + # neutrons
- electrons have “no” mass

22. 5) Using the diagram, draw arrows to label the parts of the element atomic number , element symbol, element name, atomic mass

24. atomic number , element symbol, element name, atomic mass
a) In the shaded area to the right, draw the element box for the element that has an atomic mass of
b) In the shaded area to the right, draw the element box for the element that has the element symbol Pt.

26. Groups: up and down columns on the periodic table -aka: Families
ORGANIZATION OF THE PERIODIC TABLE
Groups: up and down columns on the periodic table -aka: Families
Periods: side to side rows on the periodic table

27. ORGANIZATION OF THE PERIODIC TABLE
One way to classify the elements on the periodic table is by the periods and groups to which they belong.
Periods
Periods are the horizontal rows on the periodic table and are number from 1-7.
Elements in the same period have consecutive atomic numbers, but they differ predictably in their chemical properties.
Groups
Groups or families are the vertical columns on the periodic table, numbered from 1-8.
Elements in the same group usually have similar properties

28. 6)How is the periodic table arranged?
The periodic table is arranged in columns and rows.
7)What is each column on the periodic table called and how many of them are there?
Each column is called a GROUP and there are 18 of them.
8) What is each row on the periodic table called and how many of them are there?
Each row is called a PERIOD and there are 7 of them.

29. One way of organizing the periodic table….
The zigzag line or the staircase separates
Metals vs Nonmetals
9 -13

30. 9) In the diagram able, identify and highlight the zigzag line
9) In the diagram able, identify and highlight the zigzag line. What is another name for the zigzag? Label it on the diagram above.
Another name for the zigzag is the STAIRCASE. 

10) Describe where the metals are found on the periodic table. Label them “metals” on the diagram
. The metals are found on the LEFT side of the staircase. 

11) Describe where the non-metals are found on the periodic table. Label them “non-metals” on the diagram
The non-metals are found on the RIGHT side of the staircase. 

12) Which is the only non-metal element that is not located with the rest? Circle it and label it “non-metal”.
HYDROGEN is the only non-metal element that is not located with the rest. 


31. 13) Where are the metalloids found and how many of them are there?
The metalloids are found directly around the staircase. There are 8 of them. 13

32. All solids excepts mercury
State of mater METALS
All solids excepts mercury

33. State of mater of NON -METALS
Most gases except for Br which is a liquid and C, P, S, Se and I which are solids.

34. State of mater of METALOIDS
All solids

35. Properties of Metals: Good conductors of heat and electricity
Shiny (have luster)
Malleable (bendable)
Ductile (can be pulled into a wire)
Some are magnetic

36. Properties of Nonmetals:
Poor (bad) conductors of heat and electricity, non magnetic,
Solids are brittle (break instead of bend)
Non Malleable.
Generally the opposite of metals

37. Metalloids: have Properties of both metals and nonmetals
Metalloids: have Properties of both metals and nonmetals - B, Si, Ge, As, Sb, Te, Po, At

39. Chemical Reaction Equation
Fe + O2  Fe2O3
Reactants products
Above chemical reaction is in equation form
Reactants = left side (Fe and O2)
Products = right side (Fe2O3)
Reaction =Chemical change!
How do you know if a chemical reaction is happening?

40. Indicators of chemical reaction:
Temperature Change (or flames)
Color change
Gas Forms (bubbles)
Precipitation (Something solid forms, rust)
Odor Change (Smell)

41. Summary:
Metals are elements that have a luster, are malleable, and conduct electricity.
Many metals react with acids and with copper (II) chloride solution.
Nonmetals are usually dull in appearance, brittle, and do not conduct electricity.
Most nonmetals do not react with acids or with copper (II) chloride solution.
Elements that have some properties of both metals and nonmetals are metalloids.
