Germanium, atomic symbol Ge, has an atomic number of 32, and lies in group 14, on the periodic table, below silicon and to the left of arsenic. This element has four valence electrons. This makes it less reactive because it would require more energy to lose or gain four electrons. Germanium has an electronegativity of 2.01 (Pauling Scale).

Germanium. In 1869, Dmitri Mendeleev predicted its existence and some of its properties based on its position on his periodic table and called the element eka-silicon. In 1886, Clemens Winkler found the new element along with silver and sulfur, in a rare mineral called argyrodite. The first silicon-germanium alloys were obtained in 1955.

Germanium like Gallium was an element predicted by Dimitri Mendeleev through his work on the periodic table looking at tin and silicon. It was discovered by Clemens Winkler in 1886 from a silver ore sample. It was named Germanium after its countries founder's origin, Germany. Germanium being a semi-metal is crystalline and …

It has atomic number 32 and element symbol Ge. Germanium is a semimetal or metalloid that is an important semiconductor in electronics. Because it is relatively uncommon in nature, it was discovered later than most elements near it on the periodic table. The element has atomic number 32 and element symbol Ge. Fast Facts: …

Introduction. The element Germanium has an atomic number of 32 and is represented by the symbol "Ge." It's a lustrous, hard, grayish-white metalloid in the carbon group, positioned between silicon and tin. Germanium possesses semiconductor properties, making it indispensable in modern electronics like transistors and solar cells.

Recognizing that the missing component in argyrodite was a new element, Winkler dubbed it 'germanium' and proposed placing it between antimony and bismuth, based on chemical similarities with ...

The Freiberg Academy of Mining asked the chemist C. Winkler to determine the exact composition of the mineral. Analysis was comparatively easy and soon Winkler found the mineral to contain 74.72% silver, 17.43% Sulphur, 0.66% iron (II) oxide, 0.22% zinc oxide, and 0.31% mercury. But what surprised him was that the percentage of all the elements ...

Three of the missing elements were discovered within a span of time from 1875 to 1886: gallium, scandium, and germanium. Aside from the great psychological impact, they served to decisively change the attitude of the scientific world with respect to the validity of the periodic system of the elements.

In 1871, germanium (Latin Germania for Germany) was one of the elements that Dmitri Mendeleev predicted to exist as a missing analogue of the silicon group (Mendeleev called it "ekasilicon"). The existence of this element was proven by Clemens Winkler in 1886. This discovery was an important confirmation of Mendeleev's idea of element periodicity.

The prediction of an unknown element following calcium is a weak version of Mendeleev's subsequent prediction of the element we now know as scandium, discovered in 1879 [Nilson 1879]. In Mendeleev's 1871 table [Mendeleev 1871] the missing element is correctly placed between calcium and titanium, and as an analogue of yttrium. That the 1869 ...
