Atomic structure of silicon and germanium
The atomic structure of intrinsic semiconductor materials like silicon and germanium is as follows.Atomic structure of silicon
Silicon is a substance consisting of atoms which all have the same number of protons. The atomic number of silicon is 14 i.e. 14 protons. The number of protons in the nucleus of an atom is called atomic number. Silicon atom has 14 electrons (two electrons in first orbit, eight electrons in second orbit and 4 electrons in the outermost orbit).Atomic Number of Silicon is 14. Buy post box online.
Chemical symbol for Silicon is Si. Number of protons in Silicon is 14. Atomic weight of Silicon is 28.085 u or g/mol. Melting point of Silicon is 1410 °C and its the boiling point is 2355 °C.

Silicon is a typical example of metalloid, or the substance which looks like metal but does not have its properties. Its name came from the Latin word for flint, and in its pure form it looks like dark-blue metal. There is abundance of this chemical element on our planet, i.e. we can see it in the form of sand on beaches, or in the forms of various silicates. Silicon is considered to be one of the most useful metals for humanity since its alloys and chemical compounds have a large variety of useful properties. They are used, for example, for producing engines, transformers, various tools, popes, elements of roofs and windows, etc. Pure silicon is used for producing glass. As a very good semi-conductor, silicon is used for producing microelectronics, especially computers, laptops, etc.

Valence electrons are electrons located A) in the outermost energy level of an atom B) in the nucleus of an atom C) in the innermost energy level of an atom D) throughout the atom E) in the first three shells of an atom Amylose is a form of starch which has as- A) only -1,4-bonds between glucose units B) only -1,4-links bonds glucose units C) both -1,4-and -1,4-bonds between glucose units D. Valence electrons are electrons located. In the highest filled energy level of an atom in the nucleus of an atom in the innermost energy level of an atom throughout the atom in the first three shells of an atom. In the highest filled energy level of an atom. Valence electrons Electrons of an atom that have the highest energy (located in the last energy level). Valence electrons are electrons located. Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan. Electrons are sub-atomic particles that orbit the nucleus. They are not part of the nucleus, as protons and neutrons are. The term 'valence electrons' refers to the electrons that are donated.
