INTRO TO ATOMS LECTURE

INTRODUCTION TO ATOMS LECTURE

Essential Question:  What is "matter" made up of and how small are atoms?

Learning Objective:  Matter is made up of the smallest particles that can make matter: atoms

• Describe what "matter" is and what is it made up of.
• Describe the size of atoms. 

HMMM... BE READY TO PARTICIPATE

1. Can you show me an atom? Why or why not?

The pages below are from my lecture.  These pages are my own creation and I expect every student  to study them profoundly and LEARN the very important concepts I am introducing you to. By the way, this is an expectation I have for every day during the school year :). 

IMPORTANT: Take notes of lectures to study for tests and quizzes.

Atomic Models Timeline Webquest

 

Part I –  Models of the Atom

Democritus

Click the following link: http://thehistoryoftheatom.weebly.com/democritus.html

1.     How did Democritus come to his conclusions about the atom?
2.     Write two contributions Democritus gave to modern science

Dalton

Click the following link: http://www.iun.edu/~cpanhd/C101webnotes/composition/dalton.html

1.   List the 4 ideas of Dalton’s Atomic Theory

2.   Is the atomic theory still valid today?  Explain

3.   Why is he important in regards to atomic theory?

 

J.J. Thomson

Use the lecture notes and the videos in the lecture to answer these questions.

1.  What “name” is given to his model?  _________________  .  
2. DESCRIBE his model in the space below.
3. What type of rays did he use to determine the presence of electrons?
4.  What experiment did he do?

 

Rutherford

Use the lecture notes and the videos in the lecture to answer these questions.

1.  How did Rutherford describe the atom?
2. What experiment did he do?  Describe the experiment.

 

Bohr and Schrodinger 

Click on the following link: http://www.pbs.org/wgbh/aso/databank/entries/dp13at.html

1. Explain Bohr’s “planetary model”.  Where are the neutrons and protons?  Where are the electrons?
2. Complete the blanks with information from the site.   Each orbit around the nucleus represents an ________________________.    Electrons cannot exist between _________________.
3. What happens to the energy levels of the orbitals as you move further from the nucleus?
4. Bohr’s model was an improvement over the older models because he recognized that electrons had to be in _____________________ (____________________).
5. Bohr’s model needed to be improved upon because it did not work for atoms that were _______________ than Hydrogen.
6. Schrodinger predicted that electrons had electromagnetic energy, meaning that they can behave both like a ________________ and a _________________.
7. Instead of having electrons in specific orbits, they were placed in clouds in Schrodinger’s model.  In the cloud model can scientists predict where an electron is?  Explain.

9.   Can an electron be found in an exact spot within an atom? 

Part II – Summarizing The Story So Far

1. What major changes occurred from Democritus’s model to Thomson’s model?
2. What major changes occurred from Thomson’s model to Rutherford’s model?
3. What major changes occurred from Rutherford’s model to Bohr’s model?
4. What changed from Bohr’s model to the electron cloud model?

 

Part III – What is an Atom?

Click the following link:  http://www.qrg.northwestern.edu/projects/vss/docs/Propulsion/1-what-is-an-atom.html .  Read the top paragraph (only) and answer the following questions:

1. Everything in the universe (except energy) is made up of ______________________ .
2. Therefore, everything in the universe is made up of ___________________.
3. An atom itself is made up of three tiny kinds of particles called subatomic particles:  ___________, 

________________ and  __________________ .

4.  The protons and the neutrons make up the ________________ called the nucleus.

5.   The _____________________ fly around above the nucleus in a small cloud.

6.   The electrons carry a ________________ charge and the protons carry a ___________________charge.

7.    In a normal (neutral) atom the number of protons _____________________ the number of electrons.
