Week 9, Germanium
Germanium is an atomic element with an atomic mass of 32 and with properties similar to tin and silicon. Germanium is relatively abundant in the Earth's crust and has five known isotopes. Germanium's main use is as a semiconductor in transistors. Mostly, Germanium is used in fiber-optic and infra red optic. Interestingly, Germanium is one of those elements that Mendeleev predicted but never found.

I also picked geranium....I had to look up what a semiconductor is ... and found this definition: "a material that has electrical conductivity between those of a conductor and an insulator; it can vary over that wide range either permanently or dynamically." What did you find to be the insulator in geranium....I took a stab at this in my post....
