![]() The hardness of silicon carbide (SiC) is very high.Silicon has higher density in its liquid state as compared to that in solid state.Silicon is a crystalline reflective solid having bluish-tinged faces.Physical properties of silicon are listed below. The physical and chemical properties of silicon elements are listed below. Inhaling silicon dust causes a dangerous lung disease known as silicosis.Silicon is important for plants as it strengthens the plants cell wall.This is because most of the compounds found in the earth’s crust contain silicon element in them. Silicon occupies almost 27% of the earth’s crust.Silicon is also present in the meteorites.Silicon is not found naturally, but is always found as a compound with other elements.(The electrical conductivity of metals decreases with increasing temperature.) But this electrical conductivity increases with the increase in temperature. Silicon conducts electricity like the metals.Silicon is the 2nd most abundant element present in the earth’s crust.Interesting facts about silicon element are listed below. So the last electron of silicon enters the p-subshell or p-orbital. ![]() The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of silicon is 3s 2 3p 2. How can you determine the blocks-wise position of elements? Protons 14 Neutrons 14 Electrons 14 Symbol Si Atomic massĢ, 8, 4 Electronic configuration 3s 2 3p 2 Atomic radiusĢ10 picometers (van der Waals radius) Valence electronsĤ 1st Ionization energy 8.152 eV ElectronegativityĭC (Diamond cubic) Melting point 1687 K or 1414 ☌ or 2577 ☏ Boiling point 3538 K or 3265 ☌ or 5909 ☏ Density 2.33 g/cm 3 Main isotope 28Si Who discovered Silicon and when?īefore knowing this reason, first of all I want to ask you a simple question. Metalloids (Carbon group) Atomic number or Silicon Element (Si) Information AppearanceĬrystalline reflective solid with bluish-tinged faces State (at STP) Solid Position in Periodic table So if you want to know anything about Silicon element, then this guide is for you. In fact, the table mentioned below is the perfect information box (Which gives you every single detail about the Silicon element in Periodic table.)
