Where electronic charge q is in coulombs, r is the separation distance between electrons and nucleus (in an atom) in metres, the force F is in Newtons, ɛ 0 is the permittivity of free space in farads/metre, and permittivity of the free space ɛ 0 = 8.849 × 10 –12 farads/metre.įig. Now, Silicon electron configuration Si (14) 1s22s22p63s23p2 (complete configuration). The force of attraction between the nucleus (core) and the electron inside the atom is given by Silicon semiconductor, as a ‘Tetravalent’ material, has ‘four valence electrons’. 2.2 as a basis to understand the concept of covalent bond formation etc. The electron configuration of silicon is Ne 3s 3p. Silicon atom representation as a tetravalent material is shown in Fig. Silicon has an atomic number of 14, so a neutral silicon atom would have 14 electrons. Electrons extracted from valence shell and not subject to force of attraction of nucleus on them are called free electrons.Valence electrons are responsible for the chemical and electrical properties of the material.The 4 electrons in the third orbit (shell) are known as valence electrons.This last partially filled shell (third orbit) is called valence shell.

Energy levels starting from the fourth level are empty energy levels.Third orbit has the balance of 4 electrons (partially filled).Second orbit has 8 electrons (completely filled).First orbit, the inner most energy level has 2 electrons (completely filled).Each ‘Silicon atom’ has its electrons arranged in groups of energy levels or shells as the following: Now that the 2s subshell is filled, electrons in larger atoms, starting with boron, begin filling the 2p subshell, which can hold a maximum of six electrons. Why so Well this configuration determines the observed chemistry of the given element, and chemical bonds result from the sharing and transfer of electrons.which is why these electron-counting schemes are emphasized. Continuing on the periodic table to the next largest atom, beryllium, with 4 electrons, the electron configuration is 1s 2 2s 2. The planetary model for the atom is considered only from the classical model. It may be worthwhile to sit down with a text and simply write out the electronic configuration of the first 20 or so elements.Hence, the Silicon material is an ‘Electrically Neutral material’.

Thus, each atom is electrically neutral (Zero charge for the atom as a whole). The orbits are assumed to be concentric circles. It contains 14 positive charges in the nucleus and 14 electrons that move about the nucleus in closed stationary orbits.

The atomic number of Silicon atom is Z = 14.
