1. Introduction to the Periodic Table
Atomic Number ● Symbol ● Atomic Mass
Element ●

2. I made the PERIODIC TABLE !

I made the PERIODIC TABLE !

4. Trends on the Periodic Table
As you move down the periodic table, # of energy levels increases.
Size of the atom increases as you move down
As you move across, atom get smaller and electrons and protons are added.
Size of the atom decreases as you move to the right

5. What is the PERIODIC TABLE?

Organizes the elements by chemical properties.

6. How do you read the PERIODIC TABLE?

8. An abbreviation of the element name.
What is the SYMBOL?
An abbreviation of the element name.

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

10. How do I find the number of protons, electrons, and neutrons in an element using the periodic table?
# of PROTONS = ATOMIC NUMBER
# of ELECTRONS = ATOMIC NUMBER
# of NEUTRONS = ATOMIC _ ATOMIC
MASS NUMBER

But not as handsome!
Man, I look GOOD!
