Reaction

The image to the right is a picture is of a chain reaction, in nuclear chemistry, it's a continuing cascade of nuclear fissions. Reactions of this type also release a lot of energy. Where does the energy come from? Well, if you make very accurate measurement of the masses of all the atoms and subatomic particles you start with and all the atoms and subatomic particles you end up with, and then compare the two, you find that there's some "missing" mass. Matter disappears during the nuclear reaction. This loss of matter is called the mass defect. The missing matter is converted into energy. Einstein developed this into his well known equation E = mc2. In this equation, E is the amount of energy produced, m is the "missing" mass, or the mass defect, and c is the speed of light, I asked myself, what kind of "mass defect" do I have, when I start out what type of energy am I converting, am I creating positive or negative energy.
