2. Isotope Definition: form of an element with the same atomic number
What two parts of an atom remains the same if the atomic number does not change?
Protons
Electrons
What is the only thing left that changes?
Neutrons

3. A look at Hydrogen

4. What is happening in the Nucleus?
Think about a balloon that is continuously filled with air.
What will happen if you never stop filling it with air.
It will finally explode…the nucleus works the same way.

5. Isotopes of Carbon and Hydrogen

6. The explosion that results is radiation
Radiation is the release of 3 types of particles
Alpha Particles
Positivly charges and massive, these are pieces of the nucleus
Beta Particles
Negativly charged and have a very light mass, these were discovered to be the electrons
Gamma Particles
Neutrally charged and no mass, these are pure energy

7. The Strength of the Particles

8. Checkpoint What is the strongest type of particle
Gamma
How do you know it is the strongest?
Able to travel through paper and aluminum

9. Results of Radiation Radiation can be very harmful to us.
Chernobyl
Sun burns
UVA, UVB
Discover some good uses of radiation.

10. Different Uses of Radiation
Working with the student in your row..
Read the supplied article
Be able to tell the class what radiation is being used for.
Why is this use of radiation important?

11. Now let’s make some isotopes
Fill out the following chart at your seat
Atomic #
Atomic Mass
# of p
# of n
# of e
C-12
C-13
C-14

12. Draw the Bohr Diagrams for each atom in the table.

13. Make the atom using the supplies at your seat
Make the atom using the supplies at your seat. Label the parts of the atom as follows: protons = + neutrons = 0 electrons = -
