Germanium

Gillianne Gignac

Name Origin

In 1885, a new mineral named agyrodite was discovered. A scientist discovered that the mineral was made up of three different elements which were, sulfur, silver, and a new element. Clemens Winkler, the scientist that made the discovery of the new element, proposed on calling it neptunium, because of his discovery of the planet neptune, but a proposed element already had that name. So instead he chose to name it germanium in honor of his home country Germany.
