What Is The Formula For Silicon Tetrachloride
On the formula of silicon tetrachloride
The seeker asks: "What is the formula of silicon tetrachloride?" This question is related to the principle of chemistry and cannot be ignored.
The chemist explores the composition, structure, properties and changing laws of substances. Silicon tetrachloride is a compound formed by combining two elements of silicon and chlorine.
Silicon is ranked fourteenth in the periodic table of elements and is a non-metallic element. Its electron arrangement has a unique law. The outermost electron number is four, and it has a tendency to bond with other elements. Chlorine is ranked seventeenth and is also a non-metallic element. The outermost electron number is seven, and it is easy to obtain one electron to form a stable structure.
When silicon and chlorine meet, the four outer electrons of silicon respectively form a common electron pair with the unpaired electrons of the four chlorine atoms, thus forming silicon tetrachloride. Its chemical formula is expressed in concise symbols as $SiCl_ {4} $. This formula also clearly shows that the ratio of the number of atoms of silicon and chlorine in silicon tetrachloride is one to four.
Looking at this formula, it can be seen that the structure of silicon tetrachloride is in the center, and the tetrachlorine atoms surround it in the shape of a regular tetrahedron. This structure affects its physical and chemical properties. Its physical properties, at room temperature and pressure, are colorless and transparent liquids, have a pungent odor, low boiling point, and are volatile. Its chemical properties are active, and it reacts violently in contact with water to form silicic acid and hydrogen chloride.
From this point of view, the chemical formula of silicon tetrachloride, $SiCl_ {4} $, is not only a combination of symbols, but also the key to unlocking the mystery of this substance, leading us to explore its structure, properties and changes.
