7.3 Atomic And Nuclear Physics

Atomic and nuclear physics describes fundamental particles, their structure, properties and behavior. Atomic physics deals with the atom as a system consisting of a nucleus and electrons whereas nuclear physics studies atomic nuclei and their constituents and interactions. Take up the quiz below to gauge your knowledge in the field.
