The key difference between silicon and germanium is that Germanium has d electrons, but Silicon does not have any d electrons. Relevance. Your teacher is actually wrong. As noted earlier, the valence band configuration for diamond semiconductors is insensitivie to the constituents: silicon, germanium, and tin have almost identical valence band configurations, but they have quite different conduction band configurations.
First of all, I hate when this happens! Find out about its chemical and physical properties, states, energy, electrons, oxidation and more. Ge (ground state) --> [Ar] 3d10, 4s2 4p2. Can someone explain why we remove the 4s orbital first? Find out about its chemical and physical properties, states, energy, electrons, oxidation and more. Ok I get that. I thought it would be [Ar] 4s2 3d8. Furthermore, the electrons configuration of silicon is 1s 2 2s 2 2p 6 3s 2 3p 2 and the electron configuration of germanium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 2. Answer Save. An atom of Germanium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Germanium. Is this an exception for all of the elements in group 4A? Ge (+4 ion) -----> [Ar] 3d10. Boiling point The temperature at which the liquid–gas phase change occurs. Sublimation The transition of a substance directly from the solid to the gas phase without passing through a liquid phase. The four electrons are lost from the orbitals with the highest energy, the 4s and 4p. (Ge)? Germanium (Ge) has an atomic mass of 32. BII.
Therefore, as a significant difference between silicon and germanium, we can say these configurations. The electron configuration of the chemical element describes the ground state, i.e. Melting point The temperature at which the solid–liquid phase change occurs. ... Electron Configuration [Ar] 3d10 4s2 4p2: Possible Oxidation States +2,4: Electron Affinity [kJ/mol] 119: Electronegativity [Pauling scale] 2.01: 1st Ionization Energy [eV] 7.9: Year of Discovery: 1886: Discoverer: Winkler, Clemens A. 2 Answers. Lv 7. When an element ionizes to form a cation, the electrons are lost from the orbitals with the highest energy. What is the electron configuration for germanium ions? the state in which all electrons have the lowest possible energy.
Electron configuration The arrangements of electrons above the last (closed shell) noble gas. My assignment says that the configuration for Ge2+ is [Ar] 4s2 3d10. The electron configuration of Ge2+ is [Ar] 4s2 3d10 Below I drew out exactly what will happen when you remove (+2) 2 electrons from the Germanium ion (Ge). When the atom is in excited state, one or more electrons go to a higher energy state, so electron configuration of the excited atom is different . But then it says, for Ge4+ [Ar] 3d10.
