The s, p, d, and f subshells therefore can accommodate a maximum of 2, 6, 10, and 14 electrons respectively. A value of ‘ℓ’ can indicate either an s, p, d, or f subshell that varies in shape. It is denoted by the symbol (ℓ) and its value is equal to the total number of angular nodes in the orbital. The azimuthal quantum number (also known as ‘ℓ’) is the shape of an atom’s orbital. Subshells have labels such as s, p, d, and f. Each subshell is separated by an electron orbital. Subshells are electron shells formed by subdividing the principal shell of electrons. Moreover, electrons in outer shells can travel farther from the nucleus than electrons in inner shells. The 1s and 7s in the outermost shell have more energy than those in the inner shells. The electron shells are labeled K, L, M, N, O, P, and Q or 1, 2, 3, 4, 5, 6, and 7. The shell number is represented by the formula 2n 2, where n is the shell number. The number of subshells describes the shape of the orbital. It refers to the size of the orbital and the energy level of electron places. Shells are explained by the principal quantum number (n), which describes the energy of an electron and its most probable location in an atom.

How To Write Electron Configurations Shells or Orbits Note that this arrangement is of keen importance in the study of the physical and chemical properties of the elements of the periodic table. It describes how electrons are arranged in atoms and molecules. For instance, the s-p-d-f blocks of the periodic table are defined based on electron configuration.Įlectron configuration is the fundamental concept in electron theory. All elements of the periodic table can be classified into groups based on electronic configurations. The number and position of an atom’s electrons are referred to as its electron configuration. Electrons are negatively charged particles orbiting around the positively charged nuclei of atoms.
