ATOMIC STRUCTURE AND RADIOACTIVITY

Atomic structure

BUY THE

PRESENTATION!

Ionising Radiation! The stuff of science fiction nightmares! An invisible killer that detroys living

things! Murdered spies! Nuclear disasters! Radioactive waste! Nuclear destruction. It is vital that

we understand this natural phenomena. This is the page to do so….. But before we can

understand what ionising radiation is, we first need to understand the structure of the atom…..

has the same number of protons but a different number of neutrons

DEFINE THE FOLLOWING WORDS

nucleus

atomic number

atomic mass

ion

Describe what is happening in these two diagrams?

The atom absorbs em radiation and the electron moves up to a higher orbit before falling to a lower orbit and emitting em radiation

ionisation via absorbtion of electromagnetic radiation
