Carbon (C), silicon (Si) and germanium (Ge) have the same lattice structure and their valence electrons are 4. These valence electrons are the covalent bonds that hold the crystal together. Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. Answer to How many valence electrons does Ge (germanium) have? The valence electrons are colored red while the core electrons are in black. Note that the center atom (and the others by extension) has completed its valence shell by sharing electrons. A. Mesopotamia, around 500 BCE B. Egypt, around 800 BCE C. Mesoamerica, around 1000 BCE D. Harappa, around 2000 BCE. In the neutral atom, 32 electrons are present. Valence electrons are the electrons which are in outer shell of the atom. Electron Configuration, [Ar] 3d10 4s2 4p2. Maybe add your school logo, work team or anything else to maker your paper look cool? There are 4 electrons in outer shell of Ge atom at ground state. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than germanium. 2s. Thus, germanium has 28 core electrons. For C, these electrons are in the second orbit, for Si it is third and for germanium, it is the fourth orbit. In the case of Germanium the valence electrons is 2,4.
