Silicon has 14 electrons out of which 4 valence electrons are present in the 3s2 3p2 outer orbitals of atom. How many valence electrons does a Silicon atom have? It is located in group 14 and period 3 in the modern periodic table. Silicon is the 14 element on the periodic table. Silicon is a chemical element with the symbol Si and atomic number 14. What is the position of Silicon in the Periodic Table? Silicon is a chemical element with symbol Si and atomic number 14. To form abbreviated notation of electronic configuration, the completely filled subshells are replaced by the noble gas of the preceding period in square brackets. The abbreviated electronic configuration of Silicon is 3s2 3p2. What is the abbreviated electronic configuration of Silicon? The electronic configuration of Silicon is 1s2 2s2 2p6 3s2 3p2. What is the electronic configuration of Silicon? Silicon Thermal Properties - Enthalpies and thermodynamics Optical Properties of Silicon Refractive IndexĪcoustic Properties of Silicon Speed of Sound Silicon Magnetic Properties Magnetic Type Silicon Heat and Conduction Properties Thermal Conductivity Refer to table below for the Electrical properties ofSilicon Electrical Conductivity Hardness of Silicon - Tests to Measure of Hardness of Element Mohs Hardness For definitions of ionic radius and further information, follow the hypertext link.Refer to below table for Silicon Physical Properties DensityĢ.33 g/cm3(when liquid at m.p density is $2.57 g/cm3) Further information is available in inorganic chemistry textbooks, usually at Level 1 or First Year University level. The terms low spin and high spin refer to the electronic configurations of particular geomtries of certain d-block metal ions. For electronic configurations, where it matters, the values given for octahedral species are low spin unless stated to be high spin. Size does depend upon geometry and environment. In this table, geometry refers to the arrangment of the ion's nearest neighbours.

The R max values for neutral gaseous element valence orbitals are abstracted from reference 1. Image showing periodicity of valence s-orbital radius for the chemical elements as size-coded balls on a periodic table grid. Table: valence shell orbital radii for silicon. Two values are given here, one is based upon calculations and the other upon observation - follow the appropriate link for further details. The problem is its meaning, which is clearly very different in different sources and books. The term "atomic radius" is not particularly helpful although its use is widespread. Follow the appropriate hyperlinks for definitions of each radius type. The size of neutral atoms depends upon the way in which the measurement is made and the environment. All values of radii are given in picometres (pm). Follow the appropriate hyperlinks for literature references and definitions of each type of radius. There are several other ways ways to define radius for atoms and ions. It is not always easy to make sensible comparisons between the elements however as some bonds are quite short because of multiple bonding (for instance the O=O distance in O 2 is short because of the the double bond connecting the two atoms. One measure of size is the element-element distance within the element.
