Question

1.) Use what you have learned about atomic structure to compare the number of subatomic particles in oxygen and the radioactive isotope of oxygen known as Oxygen

-15 ( frequently used in PET scanning). List the number of protons, neutrons, and electrons that would be found in each. List the number of protons, neutrons and electrons in oxygen and list them in THAT order. Then, list the last three the in numbers of protons, neutrons, and electrons in oxygen

-15 and list them in that order.

See below for format:

a. Blank 1 - protons in 1 atom of oxygen

b. Blank 2 - neutrons in 1 atom of oxygen

c. Blank 3 - electrons in 1 atom of oxygen

d. Blank 4 - protons in 1 atom of oxygen-15

e. Blank 5 - neutrons in 1 atom of oxygen-15

f. Blank 6 - electrons in 1 atom of oxygen-15

2.) What is a PET scan?

3.) Why must Oxygen-15 be used instead of regular, non-radioactive oxygen?

4.)

In addition to PET scanning, list two other ways in which radioactive isotopes can be

used clinically.
