Ohh Man, Do WE Have To Have A Grade???

The Text Book

• This Book will be an integral Part of the course. Test and Quiz material will come from the reading along with the class lectures.

Where Do You Find Chemistry?

You find it in places that you haven’t thought of before

• Just Like Wilhelm Roentgen

Where Do You Find Chemistry?

You find it in terms of Energy

• Things that burn and explode

Where Do You Find Chemistry?

You find it when things mix

• Watch Out – You Never Know

What Is In A Chemists Flask

So What Is Chemistry• Well, it’s the study of matter and the

changes it undergoes.

• Ohh, that is like, sooooooo booooring……

• Well wait, the changes we just saw weren’t so bad, maybe chemistry can be cool!!!!

Chemistry Lingo

Matter – The stuff everything is made of

Atom – A small building block of matter used to make larger substances

(They are listed on the periodic table)

Periodic Table – Table of atoms or elements (plural)

Group – column on the periodic table

Period – row on the periodic table

So What’s An Atom Anyhow?

• Atoms are small particles that act as building block for larger substances.

Think of it like Lego Building Blocks. The Blocks represent atoms and with those you can make castles, air planes, cars, and sky scrapers.

                  

      

Atoms• Atoms are composed of three small

particles– Proton – Positive charged particle in center

or nucleus of an atom with a mass of 1 amu– Neutron – Neutral charged particle in

nucleus of an atom with an mass of 1 amu– Electron – Negative charged particle that is

outside and around the nucleus with a mass of 1/1837 amu.

How Do We View Atoms

Old View – sun and Planets – not correct

Modern view – electron density

How Do We View Atoms

• What about size

E1 - Hallway

E2 – WalMart

E3 – Salt Lake

E4 – Kansas City

Wow, that’s a whole lot of nothing – how can nothing be something? Well it’s all chicken wire!!!
