The formula 2*(2l + 1) gives the maximum number of electrons that a subshell can accommodate. Before drawing the orbital diagram, you should know the three general rules. In practice, no known atoms have electrons in the $g$ or $h$ subshells, but the quantum mechanical model predicts their existence. What exactly is an element's electron configuration? Selenium Valence Electrons - Learnool First, we look at the n=1 shell (the first shell). The Aufbau principle states that electrons will occupy lower energy orbitals before moving on to higher energy orbitals. Thus the $p$ subshell has three orbitals. p has 3 orbitals and d subshell has 5 orbitals. The maximum number of electrons that can be accommodated in a shell (n) is determined by the principal quantum number. We can think of an atom like a hotel. Electron Configuration Chart for All Elements in the Periodic Table Each shell (or energy level) has some number of subshells, which describe the types of atomic orbitals available to electrons in that subshell. The numbers 1s 2s 2p 3s 3p represent electron orbital energy levels. Jayden Arevalo 2K wrote: The number of orbitals depends on the subshell. Each subshell is separated by an electron orbital.
