Gemel - Germanium Trading Card

The wizard, Gemel represents the element, Germanium in the Magical Elements of the Periodic Table. Gemel has a special staff with a Germanium tip that can do some cool tricks with cameras. She can make images blurry, change the colors, or even make them disappear completely. This can be used to fool people or stop cameras from working properly. The name comes from the Latin germania for Germany. Germanium does not react with water or air, and the only acid that can affect it is nitric acid. Like gallium, silicon, bismuth and antimony, it expands when it freezes. Pure germanium can grow long, thin structures called germanium whiskers. These can get in the way and cause problems in gadgets like diodes and transistors by creating electrical shorts when they touch other parts. Germanium’s value was first recognized in 1945 during World War II when it was used in high-resolution radar receivers. The first germanium transistor was invented shortly after.
