What’s up world! In science we have been studying what atoms look like and what they do. We had a test where we had to recreate an atom as acuratly as we could using a 3D printer website. We only had 15 minutes to do it. We had a choice between Hydrogen, Helium, Lithium and Beryllium and I chose Helium. Here it is:

OK, now I will explain to you what in the world all of the spheres are in this picture. The green spheres in the middle are called Protons. The blue spheres in the middle are called Neutrons. The two red spheres on the outside are called electrons and electrons have to be the same amount as protons to have a stable atom because, protons are +1 and electrons are -1 so they cancel each other out.
