What Is Silicon’s Electron Configuration?

The electron configuration of silicon is 1s2 2s2 2p6 3s2 3p2. The electron configuration of silicon can be written as Ne 3s2 3p2 in noble gas notation.

Silicon has the chemical symbol Si, atomic number 14, and a relative atomic mass of 28.085 in the periodic table of elements. It has 14 protons and 14 electrons, with 14 neutrons in its most prevalent isotope.

The number of electrons located on each orbital shell and subshell of a neutral atom is depicted in the electron configuration of an atom, which is the fundamental unit of an element. S, p, d, and f are the four types of orbitals. These orbitals’ subshells can hold up to two electrons for the s subshell, six electrons for the p subshell, ten electrons for the d subshell, and fourteen electrons for the f subshell. When electrons are assigned to specific orbitals, they must first occupy the principal energy levels before going on to the next.

Silicon has fourteen electrons dispersed across five energy levels. With 2, 2, 6 and 2 electrons, the orbitals 1s, 2s, 2p, and 3 are filled first. The final two electrons are assigned to the 3p orbital. The noble gas notation is sometimes used to express the electron configuration, offering a quick way to write the electron dispersion in an atom.
