The 14th aspect of the periodic table is silicon. Silicon is a semiconductor product and, its prize is ‘Si’. Silicon participates in the formation of bonds through its valence electrons. This article discusses in information the valence electrons of silicon(Si).

What space the valence electrons of silicon(Si)?
The second element the group-14 is silicon, i beg your pardon is a semiconductor material. Silicon materials are used in various electronic devices. Silicon needs to be doped for usage in electronic devices devices. During doping, one electron is attached to or removed from the valence electron that silicon.
The valence electron is the total number of electrons in the last orbit(shell). The total number of electrons in the critical shell(orbit) ~ the electron configuration of silicon is called the valence electrons of silicon(Si).
The electron construction of silicon in excited state is Si*(14) = 1s2 2s2 2p6 3s1 3px1 3py1 3pz1. Here, the electron construction of silicon(Si) shows that 4 unpaired electron exist. Therefore, the valency(valence) the the silicon(Si) atom is 4.
How many valence electrons does silicon ion have?
After the electron configuration, the last shell(orbit) that the silicon atom has 4 electrons. In this case, the valence(valency) and also valence electrons of silicon space 4.
Elements that have four electrons in their last orbit cannot obtain or disapprove electrons to complete their octave. These elements have come share electrons with other facets to complete the octave.
As silicon has 4 electrons in its last orbit, silicon completes the octave by share four more electrons with another element. Together silicon has 4 electrons in its critical orbit, silicon completes the octave by sharing four an ext electrons with an additional element.
As a result, silicon fills its octave and also comes come a steady state. We view that silicon repurchase the electron construction of the inert gas argon. Native the over discussion, we deserve to say the the valence electrons of silicon ions are eight.
Compound formation of silicon(Si)
Silicon(Si) participates in the formation of bonds v its valence electrons. We recognize that the valence electron in silicon(Si) room four. This valence electron participates in the development of bonds with atoms of various other elements.
Silicon atoms kind bonds by sharing electrons with oxygen atoms. The electron construction of oxygen shows that the valence electrons of oxygen space six. Two oxygen atoms and also one silicon atom make Silicon dioxide(SiO2) compounds by share electrons.
As a result, the silicon atom completes that is octave and also acquires the electron configuration of the argon. On the other hand, oxygen repurchase the electron configuration of neon.

Therefore, a silicon atom shares electrons with two oxygen atom to form the silicon dioxide(SiO2) compound v a covalent bond. Silicon dioxide(SiO2) is a covalent bond.
