An introduction to Atomic and Nuclear Physics;
Eleven weeks of learning through the Uttoxeter U3A

Welcome to an opportunity to learn about Atomic and Nuclear Physics; together with the necessary underpinning knowledge.

This web page is a work in progress with the intention of providing access to information to support your learning.

An introduction and the structure of the atom

Protons, neutrons, electrons. the classic model of the atom. Rutherford scattering; evidence for small, dense, positive nucleus.

Here you can see a mind map of the subject and how it breaks down into sub-areas. Here are Jenny's notes for the session.

Atomic number and the Periodic Table

Continue from session 1 if necessary.  Organisation of elements into the periodic table. Mendeleev. Isotopes.

Here are Jenny's notes for the session and here is a link to a Web version of the Periodic Table; rich with extra information. Here is a link to more information about elements in the Periodic Table; from Wikipedia
