Silicon - Si It is known that silicon forms compounds with 64 out of the 96 stable elements and possibly form silicides with other 18 elements. Appart from metallic silicides, which are used in big quantities in metallurgy, it forms important commonly used compounds with hydrogen, carbon, halogens, nitrogen, oxygen and sulphur.

Silicon Silicon is a chemical element with symbol Si and atomic number 14. It is a tetravalent metalloid, more reactive than germanium, the metalloid directly below it in the table. Controversy about silicon's character dates to its discovery; it was first prepared and characterized in pure form in 1823.he isotopes of silicon range in mass number from 22 to 44. The most common decay mode of six isotopes with mass numbers lower than the most abundant stable isotope, silicon-28, is β+ , primarily forming aluminium isotopes (13 protons) as decay products.

- Silicon is a solid at room temperature, with relatively high melting and boiling points of 1414 and 3265 °C, respectively. Like water, it has a greater density in a liquid state than in a solid state, and so, like water but unlike most substances, it does not contract when it freezes, but expands.

Silicon - Si Silicon is the most abundant electropositive element in The Earth’s crust. It’s a metalloid with a marked metallic luster and very brittle. It is usually tetravalent in its compounds, although sometimes its bivalent, and it’s purely electropositive in its chemical behaviour. Moreover, pentacoordinated and hexacoordinated silicon compounds are also known.

Atomic Properties and the Periodic Table All chemical elements can be classified as either metals, nonmetals, or metalloids. Metals generally have the following physical properties: they are lustrous, malleable (they can change shape without breaking), ductile (can be pulled into wires), and they are very good conductors of heat and electricity.

Structure and bonding? SiCl4 is covalent compound. Si--Cl bond is polar because Cl is more electronegativity than Si. Structure of SiCl4 molecule is tetrahedral. THis structure is symmetry which brings to the non-polar characteristic of SiCl4 molecule. This is because all the dipole moment in Si--Cl bond cancel out each other.The bond between Si--Cl is covalent bond.ollow. The geometry of a silicon tetrachloride (SiCl4) molecule is TETRAHEDRAL. The molecule consists of a central Si atom, which has a coordination number of 4. Four chloride (Cl) atoms can bond to Si.
