Silicon is a chemical element with symbol Si and atomic number 14. It is a hard, brittle, and unreactive metalloid and semiconductor that is essential for plants and widely used in electronics and solar cells.
A data page showing the electron configurations of the neutral gaseous atoms in their ground states, with subshells and numbers of electrons. The configurations are given by the Aufbau principle and the Madelung rule, with exceptions and predictions for undiscovered elements.
Learn how to describe the distribution of electrons in atoms or molecules using shells, subshells, and orbitals. See examples, notation, and applications of electron configuration to the periodic table and chemical bonds.
A table that shows the electron configurations of the chemical elements in the ground state, based on their atomic numbers and subshells. The table also includes predictions for elements 109–118, and indicates the noble gas symbols and subshells for each element.
Hund's rules are a set of rules to determine the ground state of a multi-electron atom based on electron configuration, spin, and orbital angular momentum. Learn the three rules, their physical explanations, and examples for silicon and titanium.
The carbon group is a periodic table group consisting of carbon, silicon, germanium, tin, lead, and flerovium. It has four elements with four valence electrons and various chemical properties, such as covalent bonding, hybridization, and electron-precise alkyl derivatives.
Doping is the introduction of impurities into a pure semiconductor to modify its electrical, optical and structural properties. Learn about the history, types, effects and applications of doping in semiconductor production and devices.
The first molar ionization energy applies to the neutral atoms. The second, third, etc., molar ionization energy applies to the further removal of an electron from a singly, doubly, etc., charged ion. For ionization energies measured in the unit eV, see Ionization energies of the elements (data page). All data from rutherfordium onwards is ...
