What is the atomic structure of silicon and germanium?

Solid state electronics arises from the unique properties of silicon and germanium, each of which has four valence electrons and which form crystal lattices in which substituted atoms (dopants) can dramatically change the electrical properties.

What is the atomic structure of a semiconductor?

The atoms of semiconductors are arranged in an ordered array called crystal lattice because they have a crystalline structure e.g., germanium and silicon. Since both these materials are tetravalent having four valence electrons in their outermost shell, therefore they form covalent bonds with the neighbouring atoms.

How many protons and electrons are in a germanium atom?

Name Germanium
Atomic Mass 72.61 atomic mass unit
Number of Protons 32
Number of Neutrons 41
Number of Electrons 32

What do all germanium atoms have in common?

It is classified as a metalloid. It is similar in properties to the other metalloids near it in the periodic table which are silicon and arsenic. Germanium atoms have 32 electrons and 32 protons with 4 valence electrons in the outer shell.

Why is it called germanium?

Germanium is metalloid, which means it has properties of both metals and nonmetals. The name “germanium” comes from the Latin name for Germany, named for Winkler’s home country, according to the Jefferson Lab.

Is germanium nonmetal or metal?

Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.

Is germanium used in phones?

Despite its failure as a transistor in the 1950s, germanium is now used in tandem with silicon in transistor components for some cell phones and wireless devices.

Is Group 13 metal or nonmetal?

boron group

How many metals are there in total?

Metals are arranged on the left side of the periodic table and there are five kinds of metals: Alkaline earth metals, Alkali metals, Transition metals, Actinides and Lanthanides. There are a total 92 elements out of which 70 are metals.

How many nonmetals are there in total?

Seventeen elements are generally classified as nonmetals; most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon); one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine).
