NUCLEAR

Here is a very simple Rutherford scattering with a nuclear atom.

The simple display of nuclei radioactively decaying with a plot of the number left, is useful.

Beta decay is here shown as diagonal moves on the n-p plot.  Simple but graphic.

More radioactive decay; this beautiful applet enables you to select a parent isotope at the start of a radioactive decay chain, and then watch, on the Z/N chart (unfortunately the 'wrong' way round) as the decay chain unfolds.  Hovering over each isotope gives relevant information on it.

This shows the workings of an ionisation-type smoke alarm nicely.

Nuclear power plant.  Stop it blowing up...

A simple simulation of a chain reaction.

This is a clever one. Choose a gas, it displays its emission spectrum, and under it a trial spectrum area, and a section where you can put in energy levels, and transitions, which, if they are in the right frequency range, are displayed to compare with those of the actual element. Nice stuff!  This is the same, but just for Hydrogen.)
