MineChem

MineChem is a mod originally by ljdp, then maintained by Rush12, now maintained by jakimfett and pixlepix. This mod is all about science; particularly chemistry and basic physics. Materials in Minecraft can all be broken down into basic compounds and elements with MineChem, which can then be turned back into other compounds and materials, like can be done with real-life chemistry. Base elements can even be split using a Fission Reactor, or combined with a Fusion Reactor.

MineChem has 113 elements, which differs from real-life, as there are truly 118 known elements. All elements included in MineChem exist in the real world. The elements that are not included in MineChem are Flerovium, Ununpentium, Livermorium, Ununseptium, and Ununoctium.
