![]() ![]() These are the electrons located in the outermost shell of the atom, which in the case of silicon is the third shell. In summary, the electron distribution in the shells of a silicon atom is 2, 8, 4 for the first, second, and third shells, respectively. The third shell can hold a maximum of 18 electrons, but in the case of silicon, it only contains 4 electrons (2 in the 3s subshell and 2 in the 3p subshell).The second shell can hold a maximum of 8 electrons, and in the case of silicon, it contains 8 electrons (2 in the 2s subshell and 6 in the 2p subshell).The first shell (closest to the nucleus) can hold a maximum of 2 electrons, and in the case of silicon, it contains 2 electrons (in the 1s subshell).The electron distribution in the shells of a silicon atom can be summarized as follows: ![]() Distribution of Electrons in Shell in Silicon Atom These four electrons are available for chemical bonding and are responsible for the unique chemical properties of silicon.Īlso Read: Electron Configuration of Cobalt 3. The valence shell of silicon, which is the outermost shell, contains four electrons in the 3s and 3p subshells. In simpler terms, silicon has 14 electrons, with two electrons in the 1s subshell, two electrons in the 2s subshell, six electrons in the 2p subshell, two electrons in the 3s subshell, and finally, two electrons in the 3p subshell. The electronic configuration of silicon is 1s 2 2s 2 2p 6 3s² 3p², where 1s 2 2s 2 2p 6 represents the electron configuration of the noble gas neon, and 3s² 3p² represents the valence shell electronic configuration of silicon. It is also used in the production of silicones, which are widely used in various industries for their thermal and chemical stability. Silicon is also an important element in the formation of minerals, such as quartz and feldspar, which are essential components of many rocks. This makes it an ideal material for covalent bonding with other elements, especially other elements in Group 14 of the periodic table, such as carbon and germanium. Silicon has a diamond crystal structure, and it has four valence electrons in its outermost shell. Silicon is the second most abundant element in the Earth’s crust after oxygen, and it is widely used in the electronics and semiconductor industry to make computer chips, solar cells, and other electronic devices. It is a semiconductor, meaning that it has electrical conductivity intermediate between that of a metal and an insulator. Silicon is a metalloid, which means it has properties of both metals and nonmetals. It is a hard, brittle crystalline solid with a blue-grey metallic lustre. Silicon is a chemical element with the symbol Si and atomic number 14. ![]()
