UNIT 2
MODULE 3: ATOMIC AND NUCLEAR PHYSICS (cont’d)

SPECIFIC OBJECTIVES EXPLANATORY NOTES SUGGESTED PRACTICAL
ACTIVITIES

Atomic Mass (cont’d)

Students should be able to:

3.7. illustrate by examples the Naturally occurring
conservation of nucleon processes such as
number, proton number, spontaneous decay of
energy and charge in nuclear radioactive elements, as
reactions; and, well as nuclear fission and
nuclear fusion should be
referenced.

3.8. interpret nuclear reactions Briefly review isotopes.

Students should be able to:

4.1. relate radioactivity to Refer to Specific Objective

Sketch the exponential
nature of radioactive decay.

4.3. identify the origins and The deleterious effects of
environmental hazards of high energy radiation on
background radiation; living tissue should be
highlighted.

4.4. describe experiments to
distinguish between the
three types of emissions
from radioactive substances;
