Atomic number: 32
Year discovered: 1886
Discovered by: Clemens Alexander Winkler (1838-1904), a German chemist.
- Winkler analyzed silver ore and, when he had completed his work, he found that the elements he had located added up to only 93 percent of the whole.
- Puzzled, he searched out the remaining 7 percent and, in 1886, he found a hitherto unrecognized element, which he named “germanium” for Germany.
- Germanium was discovered in a mineral called argyrodite.
- Germanium was an element whose existence was predicted by D. I. Mendeléyev in 1871.
- He suggested that the then unknown element germanium should resemble silicon in its properties.
- He also suggested; therefore, the name eka-silicon (symbol Es).
- His predictions for the properties of germanium are remarkably close to reality.
- Three predictions were made, three predictions were fulfilled.
