I have added functions to calculate the mass number and the charge on each configuration. Then I have added the properties of each element in the periodic table into the code and made a div so that it can be seen in the web page. In the video below I am changing the number of electrons and protons to showcase it working I am yet to add an input on the screen. Also for each element I have added its atomic number, symbol, name, atomic mass, period, group and category. I believe it will prove useful in the future when I add a proper description. I am also going to add isotopes in the future. It was very boring to copy all the elements from he periodic table though. Thanks for reading!!

edit: I just noticed a bug. I am not changing the number of neutrons so the mass number is wrong in every case. As I set the detection of each element by the number of protons I didn’t realise it. Sorry for the error
