Unit 2 On Atoms and Such

Our second unit of study for this year will focus on the atom, the smallest unit of matter that retains its unique properties.

"What? I don't understand a word you are saying, Mr. Finke!"

That's okay, you'll pick it up over time and with practice during class. Meanwhile, take some time to head over to science-class.net and check out the slideshow called "The Atom 2" for some review help. Out of all the models shown on that slideshow, you are only required to learn how to draw the BOHR model.



In order to draw a Bohr model, you really need to know the three all essential
ATOMIC RULES!!!
Atomic # = # of Protons (P)
Atomic # = # of Electrons (E)

Atomic Mass = P + N

"Uhh, okay Mr. Finke, but I still have no idea where to get
that information."


Ah, yes. The actual information about each type of atom is found
in the Periodic Table.
Here is an
example.
This link will give you all the information about each element.
We really only focus on the first 18 elements in the 6th grade.


You should also know
:

How to determine what element is being represented by a Bohr
model shown to you. IF the model shown has 6 protons it must be a
atomic model of Carbon, because only Carbon has 6 protons. 8 protons
would have to be Oxygen, etc....

You need to know that table salt is a compound made up of Sodium
(Na) and Chlorine (Cl).
You need to know that Rust is made of Iron (Fe) and Oxygen (O).
You need to know that we cannot cut an atom of anything in half and
still have that same element, therefore an atom is the smallest unit of
an element that is still that element.
