![]() ![]() Silicon atoms form bonds by sharing electrons with oxygen atoms. This valence electron participates in the formation of bonds with atoms of other elements. Silicon(Si) participates in the formation of bonds through its valence electrons. From the above discussion, we can say that the valence electrons of silicon ions are eight. We see that silicon acquires the electron configuration of the inert gas argon. As silicon has four electrons in its last orbit, silicon completes the octave by sharing four more electrons with another element.Īs a result, silicon fills its octave and comes to a stable state. These elements have to share electrons with other elements to complete the octave.Īs silicon has four electrons in its last orbit, silicon completes the octave by sharing four more electrons with another element. In this case, the valency and valence electrons of silicon are 4.Įlements that have four electrons in their last orbit cannot receive or reject electrons to complete their octave. How many valence electrons does silicon ion have?Īfter the electron configuration, the last shell(orbit) of the silicon atom has four electrons. Here, this electron configuration shows that the last shell of the silicon atom has four unpaired electrons(3s 1 3p x 1 3p y 1 3p z 1). The electron configuration of silicon in excited state is Si*(14) = 1s 2 2s 2 2p 6 3s 1 3p x 1 3p y 1 3p z 1. ![]() Valency and valence electrons of silicon(Si) Valency is determined from the electron configuration of the element in the excited state. The number of unpaired electrons in the last orbit of an element is the valency of that element.Īs we know, ground state electron configuration of silicon is 1s 2 2s 2 2p 6 3s 2 3p 2. The ability of one atom of an element to join another atom during the formation of a molecule is called valency(valence). Therefore, the valence electrons of silicon are four. The electron configuration of silicon shows that the last shell of silicon has four electrons. The total number of electrons in a valence shell is called a valence electron. The last shell after the electron configuration is called the valence shell. The third step is to diagnose the valence shell. Step-3: Determine the valence shell and calculate the total electrons That is, the first shell of silicon has two electrons, the second shell has eight electrons and the 3rd shell has four electrons. The valence electrons determine the properties of the element and participate in the formation of bonds. The total number of electrons in the last shell after the electron configuration of silicon is called the valence electrons of silicon. The valence electron is the total number of electrons in the last orbit(shell). Silicon has to be doped for use in electronics devices.ĭuring doping, an electron is attached to or removed from the valence electron of silicon. Silicon materials are used in various electronic devices. The second element of group-14 is silicon, which is a semiconductor material. What are the valence electrons of silicon? Therefore, the number of neutrons in silicon is 14. We know that the atomic number of silicon is 14 and the atomic mass number is about 28(28.084). That is, neutron number (n) = atomic mass number (A) – atomic number (Z) The number of neutrons in an element is obtained from the difference between the number of atomic masses and the number of atoms. That is, a silicon atom has a total of fourteen electrons. Electrons equal to protons are located in a circular shell outside the nucleus. That is, the number of protons in silicon is fourteen. ![]() The atomic number is the number of protons. Protons and neutrons are located in the nucleus. The nucleus is located in the center of the atom. How many electrons, protons and neutrons does silicon have?
