A microscope for Germanium to replace LED. The changes are:
As suggested by Blue Lightning: LED for Gallium instead of Germanium who is now represented with a microscope.
The old microchip for Gallium, represent Arsenic instead now.
Made another variation to the radioactive-icon, so there is more to choose from. J is from the first version (K), but with a black dot in the middle (thanks to the commenter's).
A to I is the new ones. They are all the same with different colors, except C who also have added transparency to the far out parts of the rings.
Since many elements is going to be represented by the radioactive-icon, I may try out more ideas later.
