SQUARE OF THE PERIODIC TABLE NOTES
ATOMS OF ELEMENTS ARE ABLE TO COMBINE IN MILLIONS OF DIFFERENT WAYS.
__________________________________________

Today, we are going to start talking about the PERIODIC TABLE. The periodic table is a way for
scientists to
_______________________ .
Each element on the periodic table has its own square. We’re going to label a square in
the space below.
ATOMIC
NUMBER:
ELEMENT NAME:
8
O
Oxygen
15.9994
So let’s make sure that we are clear……
The number of protons is equal to _____________________________
The number of electrons is equal to ____________________________
Protons = Electrons
The number of neutrons = _____________ - ______________
What is the difference between atomic mass and the atomic number?
CHEMICAL
SYMBOL:
ATOMIC MASS:
We are going to spend some time looking at the periodic table and answering
questions about it—we need to make sure that we understand EXACTLY what
