Here are some videos and powerpoint shows that I’ve made for the NPA but the outcomes are the same as those in N5 Physics. Thanks to John Sharkey for the use of the Virtual Flash Physics (Int 2) and to Julian Hamm of furryelephant for the animations of ionising an atom.
If you haven’t done much Chemistry and you don’t know the process of how chemical elements are described, I suggest you check out the video below.
NB In the video above I know totally that photographs were taken well before 1896, the first being taken in 1826. Henri Becquerel discovered that Uranium, a naturally radioactive element fogs photographic film.
