Welcome back to Green World Today we're talking about nuclear fission. This energy source is quite controverial, so we're going to be looking at why. Before we begin, just a quick side note, there are multiple forms of nuclear power. This post is about nuclear fission. Nuclear decay is rarely used, most notably in some space missions. Nuclear fusion is currently being researched by scientists around the world and isn't used for commercial electricity yet. First, let's explain how nuclear fission actually works. This involves a lot of complicated chemistry and physics, but I'll do my best to explain it. Before anything else we need to look at what is in an atom. In this image, the grey represents negatively charged electrons, which circle the nucleus (plural: nuclei) in the center. The nucleus (blue and red) is made up of positively chargerd protons and neutrons (which are neutral). This means that the nucleus is positive. Th...
