4. Elements
Elements are _________ substances. That means their atoms are ______________.
pure
identical

5. Elements
The elements, alone or in combinations, make up our bodies, our world, our sun, and in fact, the entire universe.

6. Periodic Table
The periodic table organizes the elements in a particular way. A great deal of information about an element can be gathered from its position in the period table.

7. What’s in a square?
Different periodic tables can include various bits of information, but usually:
atomic number
symbol
atomic mass
state of matter at room temperature.

8. Atomic Number
This refers to how many protons an atom of that element has.
No two elements, have the same number of protons.
Bohr Model of Hydrogen Atom

9. Atomic Mass
Atomic Mass refers to the “weight” of the atom.

10. C Cu Symbols Carbon Copper All elements have their own unique symbol.
It can consist of a single capital letter, or a capital letter and one or two lower case letters. C
Carbon Cu
Copper

11. Common Elements and Symbols

12. The elements on the Periodic Table can be divided into 3 categories: metals, nonmetals, and metalloids.

13. Copper is a ______________.
Metal
Now find lead and titanium.
What side of the Periodic Table are they on?
Left!!

15. Hydrogen
The hydrogen on the metals side of the Periodic Table, but it is not a metal. Hydrogen is in a class of its own.
It’s a gas at room temperature.
It has one proton and one electron in its one and only energy level.

16. Color the Metals Green or Blue on your periodic table.
(DO NOT COLOR HYDROGEN!
Draw in zig-zag line
METALS
Do not include: B, Si, Ge, As, Sb,Te, At

17. Let’s identify some metals…..
Penny –
Aluminum –
Copper –
Iron/ aluminum -
Pounded into shapes
shines
Pulled into wires
Conducts electricity

18. Malleable
Metals can be pounded or rolled into thin sheets without shattering.

19. Luster
Shiny - reflects light from its surface

20. Good Conductor
Matter that allows electricity to flow through it easily

21. Ductile
Can be stretched into wires

22. left
Metals are on the _______ side of the Periodic Table. Properties of metals are:
Malleable, ductile, luster, good conductor

23. Opposite of a metal would be a ________________.
nonmetal
Where would I find them on the Periodic
Table?
On the opposite side!

24. Nonmetals
Nonmetals are found on the right side of the periodic table.

25. Color your nonmetals red or yellow.
Metalloids 1 2
Nonmetals 3 4 5
Metals 6 7
Metalloids: B, Si, Ge, As, Sb,Te, At

26. Let’s look at some nonmetals…..
carbon –
nitrogen-
phosphorus -

27. Opposite of a metal would be a ________________.
nonmetal
Their physical properties are also
opposite.
Good conductor –
Malleable/ductile –
Luster -

29. Metalloids are a combination of metals and nonmetals
Metalloids are a combination of metals and nonmetals. So their properties can be mixed.
An example of the properties of a metalloid
could be -
Metalloid - could be malleable with no luster or
- semi-conductor that is ductile
