This storyboard does not have a description.
so one day, a dude named Ernest Rutherford decided to use his particle and shoot particles at gold foil.
most particles went through the foil but some deflected
it turns out the nucleus was positive and dense which is why it reflected off the foil
it controls everything it does just like how our brains controls us.
what is nucleus you ask? well a nucleus is basically the brain for a atom!
the nucleus has protons and neutrons surrounded by electrons.
alpha particles have 2 protons and neutrons make is positive.
since the protons and neutrons even out, they work together and becomes a positive charge nucleus.
the nucleus is what ,makes it heavy. therefore, the reason it didn't go through.
