Electronic configuration is a fundamental concept in chemistry that helps us understand how electrons are arranged in atoms. Electrons are negatively charged subatomic particles that orbit around the nucleus of an atom. The way in which electrons are arranged in an atom determines its chemical properties, such as its reactivity, stability, and conductivity. In this blog post, we will discuss what electronic configuration is and how it is determined. Electronic configuration refers to the arrangement of electrons in the orbitals of an atom. An orbital is a region of space around the nucleus where an electron is most likely to be found. The electronic configuration of an atom describes how the electrons occupy the available orbitals. The electronic configuration of an atom is represented by a series of numbers and letters that indicate the energy levels, sublevels, and the number of electrons in each sublevel. The energy levels are numbered from 1 to 7, and each level contains one or more sublevels. The sublevels are designated by letters, such as s, p, d, and f.
